ABB PFSK152 3BSE018877R1｜ Signal Concentrator Board｜

Features
1. Multi channel high-speed pulse acquisition
Equipped with 16 independent pulse/frequency/speed input channels, it can be directly connected to encoders, speed probes, and proximity switches to collect real-time rotating equipment speed, pulse counting, and frequency signals, with high measurement accuracy and fast response speed.
2. Industrial anti-interference design
The whole board is coated with three anti moisture layers, with 2kV channel isolation, suitable for strong electromagnetic interference fields such as power plants, metallurgy, fans, compressors, etc. The pulse signal acquisition is stable without loss.
3. Multi bus communication docking
Supports industrial buses such as Profibus DP, Modbus RTU, RS485, etc., with real-time data upload to the AC800M/800xA main control, enabling remote speed monitoring, overspeed protection, and operation data recording.
4. Dedicated for equipment safety monitoring
Specially designed for rotating units such as steam turbines, induced draft fans, water pumps, compressors, etc., it is used for speed interlocking, overspeed shutdown protection, and equipment vibration matching speed collection. It is a core spare part for safety monitoring of auxiliary equipment in generator sets.
5. Channel customization configuration
Single channel parameters can be independently programmed and set, supporting pulse counting, frequency conversion, custom speed range, and adapting to different specifications of encoders and speed sensors.
