Description
Eaton IQDP4130 IQ DP-4000 Three-Phase Metering Device
Product Overview
The Eaton IQDP4130 belongs to the IQ DP-4000 family of microprocessor-based electrical metering devices used for distribution-system monitoring and voltage protection. Eaton describes the IQ DP-4000 as a compact alternative to separately installed conventional meters and switches, combining electrical measurement, protection functions, programmable I/O, and optional communications in a single package. The IQDP4130 is the three-phase version with I/O and a three-phase power supply.
The Eaton IQDP4130 accepts three-phase voltage inputs in the documented 110–600 VAC range and uses CT inputs for current measurement. Published Eaton specifications identify a 5 A current rating, 50/60 Hz operation, LED indication, and three Form C relay outputs with one synchronization pulse input. The relay outputs can be assigned to functions such as protective alarm, trip, and energy-pulse applications depending on configuration.
From a controls perspective, this is important: the IQDP4130 is not a PLC CPU or conventional I/O module. It is an electrical distribution monitoring and protection device intended to sit at the switchgear/power-distribution level. Its measurement set includes per-phase voltage and current, watts, VA, VAR, power factor, demand, energy, phase unbalance, and total harmonic distortion. Eaton documentation also identifies optional INCOM and RS-485/Modbus communication interfaces for the IQ DP-4000 family.
For legacy switchgear replacement, the exact catalog number matters. IQDP4130 identifies the three-phase supply configuration with I/O; IQDP4030 is the corresponding three-phase version without I/O. Substituting between them changes the available field interface and should not be done simply because the metering functions appear similar.
Product Introduction
Power-distribution monitoring becomes considerably simpler when voltage, current, energy, demand, protection, and relay outputs are handled by one instrument. The combines those functions with three-phase 110–600 VAC power capability and programmable I/O, making it suited to switchgear and distribution-monitoring applications.
For a legacy power-monitor replacement, however, do not stop at the catalog number. CT ratio, PT/voltage configuration, relay assignments, communication interface, and programmed protection setpoints all need to be checked against the installed device.

Major Features / Practical Advantages
Three-phase electrical measurement
The IQ DP-4000 family was designed to consolidate electrical measurements that might otherwise require several individual instruments. Eaton describes measurement of current and voltage by phase, watts, VA, VAR, power factor, energy, demand, phase unbalance and related parameters.
For a switchgear engineer, the practical benefit is straightforward: fewer separate metering devices and a common configuration point for monitoring and protection functions.

110–600 VAC three-phase input
The uses the three-phase supply version of the IQ DP-4000 platform. Eaton’s product-selection documentation identifies the y = 3 configuration as the three-phase power supply rated for 110–600 VAC.
The voltage rating should not be confused with the CT input. The device measures voltage directly according to its specified input arrangement while current measurement is based on the associated CT circuit.
Three Form C relay outputs
The I/O-equipped 4100 configuration provides three Form C relay outputs. Eaton documentation identifies these outputs as selectable for functions including trip, alarm and kWh pulse initiation. A separate synchronization input is provided for the kW utility demand window.
That makes the more than a display-only meter. The relay interface can participate in distribution-system alarming and control schemes when correctly configured.
Demand synchronization
The dedicated synchronization input is intended for utility-demand measurement. The instrument can synchronize the demand window using the external pulse, allowing the meter to align its demand calculation with the utility metering arrangement.
This becomes relevant when the is being used for facility energy management rather than simply displaying instantaneous electrical values.
Harmonic measurement
The published specification identifies voltage and current THD measurement through the 31st harmonic. That gives the a basic power-quality monitoring capability in addition to conventional voltage, current, power and energy measurements.
It should not, however, be presented as a modern high-speed power-quality analyzer. THD measurement through the 31st harmonic is useful diagnostic information, but it does not make the instrument equivalent to a dedicated waveform-analysis platform.
Voltage protection functions
The published specification gives under-voltage protection from 60–95% of nominal and over-voltage protection from 105–140%. Phase-related monitoring also includes voltage and current phase-loss functions in the IQ DP-4000 documentation.
Protection thresholds and delays must be checked against the actual programmed settings before treating catalog ranges as the installed protection scheme.
Non-volatile parameter retention
Eaton’s aftermarket documentation notes that the IQ DP-4000 retains present parameters through power failure using non-volatile memory. That is useful in legacy switchgear because a temporary loss of instrument power does not necessarily mean the programmed meter parameters disappear.
Still, a replacement device should be configured and verified rather than assuming the previous unit’s settings will somehow transfer automatically.
Communication options
The IQ DP-4000 family supports optional network interfaces including INCOM and an RS-485 Modbus interface. Eaton documentation also describes optional interfaces for data collection and PowerNet-based monitoring.
This matters when replacing an in a larger power-management system. The correct meter can still become a poor replacement if the communication module or protocol arrangement does not match the existing network.

FAQ
Is the a PLC module?
No. It is an IQ DP-4000 electrical metering and voltage-protection device. It can provide relay I/O and communications, but its primary function is monitoring and protecting electrical distribution equipment rather than executing PLC logic.
What voltage does the accept?
The three-phase version is documented for 110–600 VAC. The exact wiring arrangement and system voltage must still be checked against the installation drawings before energizing a replacement.
Does the have relay outputs?
Yes. The I/O configuration provides three Form C relay outputs. Eaton documentation identifies functions including trip, alarm and kWh pulse initiation.
Can I replace an with an IQDP4030?
Not as a functional one-for-one replacement when the existing installation uses the I/O functions. IQDP4030 is the three-phase version without I/O, whereas includes the three Form C relay outputs and synchronization pulse input.
Does the support Modbus?
The IQ DP-4000 family supports an RS-485 Modbus communication option through the appropriate communication interface. Do not assume every installation contains that option; check the actual communication module and wiring.
Can I hot-swap the ?
Do not treat it as a hot-swappable PLC I/O module. The is connected directly into a live electrical metering/protection installation, so replacement requires the applicable electrical isolation, CT/PT safety, and switchgear maintenance procedure. In particular, CT circuits must never be casually opened while energized.
Does the measure harmonics?
Yes. Published specifications identify voltage and current THD measurement through the 31st harmonic. That provides useful power-quality information, although it should not be confused with the capabilities of a dedicated high-speed waveform analyzer.
What is the current rating?
Published product specifications identify 5 A current input/rating. This is associated with the instrument’s CT measurement interface; it should not be interpreted as a 5 A load output from the meter.
Does the retain settings after a power failure?
Eaton’s IQ DP-4000 documentation states that present parameters are retained through power failure using non-volatile memory. For a replacement device, however, the installed setpoints should still be documented and verified during commissioning.
Is the still a current product?
The IQ DP-4000 family appears in Eaton’s aftermarket/renewal documentation, while the is also identified in current distributor catalogs. Because this is an older IQ DP-4000 platform, procurement should verify actual Eaton support status, revision, and replacement availability rather than assuming current-production status from distributor listings alone.
Procurement Note
When sourcing an , match the complete application, not just the catalog number. Confirm that the existing installation requires the three-phase 110–600 VAC configuration, three Form C relay outputs, and synchronization pulse input. Also verify the CT ratio and wiring, voltage connections, programmed protection thresholds, communication option, and any PowerNet/INCOM or Modbus integration.
There is a particularly important distinction between : both are three-phase IQ DP-4000 configurations, but the 4130 includes I/O. If the existing system depends on relay alarms, trip functions, energy pulse output, or demand synchronization, the lower-I/O configuration is not an equivalent substitute.
For legacy replacement procurement, Eaton’s catalog number should also be cross-checked against the older Cutler-Hammer part markings. Some documentation identifies older assembly numbers such as 66D2040G03 alongside . Do not use an old cross-reference as proof of interchangeability without checking the actual nameplate and configuration.
For new-surplus or refurbished inventory, request photographs of the actual nameplate, terminal area, display, and communication/interface modules. The condition of the relay contacts and the integrity of the voltage/current input terminals deserve particular attention because this device sits directly in an electrical distribution monitoring application.
