Built‑in function

AD198GV digital input FBM module collects potential‑free contact status signals from field switches,relays and interlock devices,then transmits discrete status data to I/A Series controller through rack backplane fieldbus. Independent surge‑suppression circuit restrains field‑side transient interference to avoid channel damage. Per‑channel LED visual diagnosis helps field technicians rapidly identify channel on‑off state and fault conditions. Hot‑swap function enables online module replacement and reduces plant shutdown risk,widely applied for interlock‑signal collection of petrochemical,power‑plant and chemical process systems.

Product Brief

AD198GV belongs to Foxboro I/A Series legacy DCS spare‑part family,obsolete original automation component. It must be matched with corresponding I/A Series baseplate and instrument rack. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
