Description
Product Overview
The Mitsubishi Electric ME110 is part of an electronic multi-measuring instrument family designed for monitoring electrical conditions in industrial facilities and power-distribution equipment. Depending on the specific model, the instrument measures quantities such as phase voltage, line voltage, current, active power, reactive power, apparent power, power factor, and frequency. These measurements help maintenance engineers assess electrical loading, investigate abnormal operating conditions, and monitor energy use. Unlike a PLC input module, the ME110 measures power-system quantities directly through its designated voltage and current measurement circuits. The exact measurement functions depend on the selected variant and wiring configuration.
Within a factory electrical system, the Mitsubishi Electric ME110 can provide local electrical readings and, on supported variants, transmit measurement data to a supervisory monitoring system. The ME110 family includes models with different output and communication arrangements. For example, the ME110SSR-4AP is listed with four analog outputs and one pulse output, while the ME110SSR-CH is associated with alarm output, digital input, and CC-Link communication functions. These are distinct configurations, not interchangeable feature sets. Before specifying an ME110 instrument, engineers should confirm the phase wiring system, rated voltage, current-transformer secondary rating, frequency, and required communication or output options.
For electrical maintenance and legacy panel replacement, the Mitsubishi Electric ME110 should be selected by its complete model code rather than the family name alone. A meter with the wrong current input rating or communication option may fit the intended application physically but fail to deliver the required measurements or signals to the control system. Check the original nameplate, panel wiring diagrams, CT and PT ratios, and monitoring-system interface before ordering. Mitsubishi Electric’s Super-S range was discontinued in March 2024 according to published product listings, making revision identification and replacement planning particularly relevant for existing installations.
Product Introduction (Non-Templated)
Incorrect meter selection can leave an electrical panel without the required alarm, analog output, or remote monitoring data—even when the display powers up normally. The Mitsubishi Electric family provides electrical measurement functions, with output and communication capabilities determined by the exact model suffix.
For a legacy power-monitoring replacement, verify the full type code, phase configuration, CT rating, and required interface before purchase. The base designation is insufficient to confirm a direct replacement.

The following models are related to the Mitsubishi Electric power-monitoring family. Their functions differ, so none should be treated as a direct substitute without checking the required configuration.
1. ME110SSR-4AP — An Super-S variant with four analog output circuits and one pulse output. Suitable when the monitoring system needs analog retransmission or pulse-based energy reporting.
2. ME110SSR-CH — A variant with alarm-output functionality, digital inputs, and CC-Link communication. Relevant where a supervisory controller requires networked monitoring and discrete status information.

Frequently Asked Questions (FAQ)
1. What does the Mitsubishi Electric measure?
The family is designed to monitor electrical parameters in power-distribution systems. Depending on the model, measured quantities include voltage, current, active power, reactive power, apparent power, power factor, and frequency.
The exact measurement list depends on the full model designation and phase-wiring configuration. Confirm the applicable documentation before relying on a particular measurement function.
2. Is the compatible with a three-phase 4-wire power system?
Documented variants support three-phase 4-wire systems, as well as certain three-phase 3-wire and single-phase arrangements.
Before connecting the instrument, verify:
- The system voltage and phase configuration.
- The rated current input and CT secondary rating.
- The correct voltage and current terminal assignments.
- The required wiring diagram for the specific variant.
Never assume that every model supports every phase configuration.
3. Does the support Modbus or CC-Link communication?
Communication support depends on the suffix. The ME110SSR-CH is listed with CC-Link, while other variants offer different output or communication arrangements.
For PLC or supervisory-system integration, verify the exact protocol, interface hardware, network settings, and required data points. A meter with analog outputs is not automatically a network-compatible replacement.
4. Can I hot-swap the while the electrical panel is energized?
Do not assume live removal is permitted. The instrument connects to electrical measurement circuits, and its terminals may carry hazardous voltages.
Before replacement, follow the site’s electrical isolation procedure and the manufacturer’s installation instructions. Confirm that the voltage circuits are isolated and that current-transformer circuits are handled safely. Never open an energized CT secondary circuit.
5. Will replacing the affect my PLC or SCADA configuration?
The meter itself is a measurement device, but replacing it with a different variant can affect the receiving control system.
For example, changing from a meter with CC-Link to one with analog outputs changes how measurements reach the PLC. Analog scaling, network addresses, alarm signals, and energy-pulse inputs may need to be reconfigured.
Record the existing settings and verify all relevant measurement values after replacement.
6. How do I confirm that a new-surplus is the correct model?
The complete nameplate designation is essential. is a family identifier rather than a sufficient ordering code.
Request photographs of the actual instrument label and terminal markings. Confirm the suffix, current and voltage ratings, phase configuration, and communication or output options. Ask for inspection and functional-test records, especially if the meter will be used for operational monitoring or alarm reporting.
7. Is the Mitsubishi Electric discontinued, and what warranty applies to surplus stock?
Published listings identify Super-S variants as discontinued in March 2024.
Warranty coverage for new-surplus stock depends on the seller’s written terms. Before ordering, confirm the warranty period, acceptance-testing window, return procedure, and whether the supplied unit has been tested for the functions required by your application.
Procurement recommendation: Please confirm the full model suffix from the nameplate—for example, ME110SSR-4AP, ME110SSR-CH, or ME110SSR-MB. That single detail determines which electrical ratings, outputs, and communication specifications can be stated accurately for your product page.
