ABB’s current product information identifies DSDP 150 as a pulse encoder input unit for 12 VDC and states that it supports pulse counting and frequency measurement with pulse generators up to 10 kHz. ABB’s older Advant OCS documentation gives the fuller S100 specification: 12 inputs, 5/12/24 V nominal pulse amplitude, 5.6 kΩ input resistance, and two galvanically isolated input groups.
Product Introduction
The ABB DSDP150, 57160001-GF, is an S100 I/O pulse counter board used in ABB Advant OCS control systems. It accepts pulse trains from field devices and provides the controller with pulse-counting and frequency-measurement information. The module has 12 pulse inputs and is designed for signals up to 10 kHz, making it suitable for monitoring rotating equipment, speed-related signals, flow pulses, and other discrete frequency sources.
The important engineering point is that DSDP150 is not a conventional digital input module. Its circuitry is intended for pulse measurement, and ABB documentation specifies optocoupler isolation between the two groups of inputs. The normal installation also involves the DSTD 150A connection unit and DSTK 160 cable, so replacing only the board without checking the termination hardware can create unnecessary commissioning problems.

Application Scenarios & Field Pitfalls
Engineering Pain Point
Legacy S100 installations often have pulse signals that cannot simply be moved to an ordinary digital-input card. A standard DI module may detect an ON/OFF state but will not necessarily provide the required frequency measurement or high-speed counting behavior. DSDP150 was specifically designed for this pulse-processing requirement.
Typical Applications
- Turbine and rotating machinery monitoring — pulse generators can provide speed-related signals for controller calculations.
- Flow measurement systems — pulse-output flow instruments can be monitored through the 12-channel pulse interface.
- Motor and shaft speed measurement — frequency of a pulse train can be used to determine rotational speed.
- Legacy Advant OCS process control systems — provides dedicated pulse inputs where the existing S100 architecture must remain in service.
Technical Pitfalls to Avoid
- Do not classify DSDP150 as a standard 32-channel digital input card. ABB identifies it specifically as a pulse input unit with 12 channels.
- Check the pulse amplitude before installation. The original S100 documentation specifies nominal 5, 12, and 24 V pulse inputs and a maximum pulse frequency of 10 kHz.
- Verify the termination assembly. The DSDP150 is documented with DSTD 150A and DSTK 160; cable and connection-unit compatibility should be checked rather than assuming a generic termination will work.

Procurement Check
For , use + 57160001-GF as the primary identification. Before ordering, confirm the installed I/O architecture, DSTD 150A termination, DSTK 160 cable, pulse voltage, and maximum signal frequency. One current ABB description emphasizes a 12 VDC application, while the older Advant documentation specifies 5/12/24 V nominal pulse inputs; for an existing plant, the installed hardware documentation and field signal should take precedence.
