Functional Features Acquires 16‑channel analog current and voltage signals from field transmitters. Built‑in HART modem reads secondary diagnostic and parameter data from HART smart instruments. Detects current loop open‑circuit and short‑circuit fault condition. Hardware over‑current protection prevents module damage under field short‑circuit fault. Transmits process value and HART diagnostic data to DCS controller via backplane bus. Front‑panel LED indicators show module power, running and fault status. Supports software parameter configuration without hardware jumper adjustment. Full mechanical and electrical compatibility with Symphony Plus SD‑series rack base unit.
Application Scenarios Power plant DCS process signal acquisition cabinet. Chemical, oil‑gas industry analog transmitter signal monitoring. Water‑treatment plant process variable measurement and control system. Symphony Plus control system spare‑part replacement and maintenance project.
Installation Requirements Insert module into designated slot of Symphony Plus SD‑series standard rack. Complete cabinet protective earth connection strictly follow system grounding specification. Field instrument wiring adopts shielded twisted‑pair cables. Separate power cable and signal cable routing. Confirm field signal range matches module input specification before power‑on.
