Product Details:

FOXBORO CM400YS is a rack-mounted FBM15 pulse input module for FOXBORO I/A Series DCS system, a high-performance DCS signal card built for process automation. This pulse input module adopts conformal coated PCB assembly and reinforced shielding frame, protecting internal precision electronic circuits from vibration, dust and electromagnetic interference inside industrial control cabinets. It can be plugged directly onto the DCS rack backplane and matched with dedicated terminal base for convenient wiring and fast maintenance. It is specially designed to collect pulse and frequency signals from field flow meters, pulse transmitters and rotary pulse sensors.

This FOXBORO CM400YS DCS signal card receives pulse or frequency signals from field pulse type instruments. It counts pulse quantity and calculates flow rate, totalized flow and rotation speed, then transmits processed data to the DCS host controller for real-time monitoring, batch counting and energy balance calculation. Each channel has adjustable signal threshold and anti-noise filtering to eliminate interference pulse and prevent miscounting. Built-in continuous self-diagnosis function monitors signal input and hardware health. It triggers alarm output once detecting open circuit and hardware fault, helping maintenance engineers quickly locate faults and reduce unplanned plant downtime. It supports hot swap operation, technicians can replace the module without shutting down the whole DCS system, which is critical for continuous production plants.
