Product Overview
FOXBORO FBMSSW (Part No. 542167) is a 16-channel dry contact digital input module dedicated to FOXBORO I/A Series DCS control system. As a core Field Bus Module (FBM), it is specially designed for industrial process control. It accurately collects passive dry contact signals from field equipment such as limit switches, level switches, button contacts and relay feedback devices, isolates and converts field switch status signals, and uploads data to the DCS main control system.
Adopting industrial isolation design, the module features strong anti-interference ability and stable long-term continuous operation, fully adapting to heavy-duty industrial working conditions in chemical, power, oil & gas and water treatment industries. FBMSSW 542167 is an original standard spare part for the system, with regular channel configuration, high signal acquisition accuracy and low failure rate. It is a universal core module for daily maintenance, module replacement and system expansion of FOXBORO I/A systems.
