Product Introduction

The ABB DSDP140B, part number 57160001-ACX, is a multifunctional high-speed pulse counter board for ABB MasterPiece PLC and Advant OCS legacy control systems. It integrates high-frequency pulse counting, digital I/O and analog output functions, acquiring encoder pulse signals to calculate position, speed and displacement for motion control applications. Adopting standard Eurocard plug-in rack structure and industrial PCB design, it maintains stable signal sampling under harsh industrial environments with vibration, temperature variation and strong electromagnetic interference. Widely applied in pulp & paper, metallurgy, power generation and mechanical motion control industries. It is an essential spare part for MasterPiece control rack maintenance, pulse measurement board replacement and old automation system renovation.

Content Details
Brand: ABB Model: DSDP140B Part No: 57160001-ACX Product Type: High Speed Pulse Counter Board Applicable System: ABB MasterPiece PLC, Advant OCS Signal: 24VDC encoder/pulse input, digital I/O, analog output Max Counting Frequency: 80kHz The ABB DSDP140B 57160001-ACX is a plug-in Eurocard module installed inside MasterPiece control rack. It is designed for high-speed pulse capture and positioning control. It receives pulse signals from rotary encoders and speed sensors, supports high-precision counting and position loop calculation. It is also equipped with digital input, digital output and analog output channels to directly output control setpoints. The module exchanges real-time measurement data, status and diagnostic information with rack CPU via backplane bus. Every unit undergoes full functional testing and aging screening before shipment to ensure reliable 24/7 continuous operation. Built-in signal filtering and surge suppression circuits filter field electrical noise and protect the backplane bus from voltage spikes. Galvanic isolation separates field signals and control side to avoid ground loop interference. It can be configured and diagnosed via ABB MasterPiece engineering software. LED indicators on the front panel display power status, pulse input activity and fault alarms, helping maintenance engineers quickly locate wiring or board faults and reduce plant downtime. Typical application scenarios include paper machine speed and position control, rolling mill encoder positioning feedback, turbine rotating speed monitoring and material length measurement. When the original pulse counter board fails, DSDP140B 57160001-ACX can be directly replaced to restore high-speed pulse acquisition and positioning function of the whole MasterPiece control system. This module complies with IEC industrial safety and EMC standards with IP20 protection rating. Compact rack layout and durable electronic components support long-term stable operation. Whether you prepare spare inventory for equipment overhaul or purchase components for legacy control system retrofit projects, the ABB DSDP140B pulse counter board provides dependable high-speed pulse and positioning signal processing for your ABB automation system.
