Description
1. Product Title
Foxboro FBM206 P0916CQ‑ 8‑Channel Channel‑Isolated Pulse Input Module, I/A‑Series Compact 200 DCS
2. Product Overview
P0916CQ (FBM206) is Compact200 pulse/frequency input fieldbus module for Foxboro I/A‑Series DCS. It receives pulse signals from turbine flow meters, vortex flow meters, pulse‑output sensors and contact pick‑ups, performs high‑speed pulse counting and frequency measurement for fiscal and process flow totalization. Each channel provides independent galvanic isolation to eliminate field noise interference. Supports maximum 25 kHz pulse‑input rate, no pulse loss within specification range. Hot‑swappable for online replacement without rack power‑down. Front‑panel LED indicators show module health status. Its upgraded compression‑style termination assembly is RH916CQ. Original manufacturing discontinued, mainly used as spare‑part replacement for petrochemical, chemical and power‑plant legacy DCS racks.
