Product Details
The 086349‑002 is 16‑channel digital output board for ABB Advant AC31 PLC control system.
This board is installed inside Advant AC31 standard rack and connects to system backplane bus. It receives control instructions from CPU unit, outputs 16‑channel 24VDC switching signals to field actuators, completes switch‑on / switch‑off control of valves, contactors and local indicators.
Front‑panel LED status indicators show channel output status and module fault alarm information for quick on‑site troubleshooting. Built‑in channel diagnosis function can detect output short‑circuit and channel failure, and feed back fault information to PLC controller. Conformal coated circuit board enhances anti‑interference performance, adapts to harsh industrial workshop environment.
It belongs to legacy Advant AC31 hardware, mainly used for spare‑part replacement and maintenance of old‑generation PLC systems. Widely applied in overhaul and renovation projects of power, chemical and papermaking industries.
It is important spare hardware for digital output loop debugging and defective 086349‑002 board replacement.
