Product Details:

FOXBORO 3C8-C3D is a rack-mounted CNT/D pulse converter card for FOXBORO I/A Series DCS, a professional industrial instrumentation for process automation. This pulse converter is a plug-in circuit board assembled with precision electronic components, fitted with shielding structure to protect internal circuits from vibration, dust and electromagnetic interference inside control cabinets. It is specially designed to receive pulse signals from flow meters and other pulse-type field sensors, then convert pulse input into standard analog signals that the DCS system can recognize for monitoring and control.

This FOXBORO 3C8-C3D DCS signal card captures pulse signals generated by field flow transmitters. It calculates flow volume and flow rate based on pulse frequency, and converts the measured value into standard 4~20mA analog signal and transmits data to DCS controller. The module supports configurable pulse scaling to match different pulse coefficients of various flow sensors. Built-in self-diagnosis function can detect signal loss and hardware fault, sending alarm messages to the DCS host system, helping maintenance personnel quickly locate abnormal points and minimize production downtime. The card adopts hot-swap design, technicians can replace the module without shutting down the whole DCS system, which is very suitable for continuous production plants.
