Product Overview

The BOU83 (D200537‑02) is 16‑channel isolated binary output module for Metso Valmet DNA DCS platform. It switches 24 VDC field loads such as solenoid valves, motor contactor coils, indicator lamps. It receives output commands from ACN‑C20 controller over internal backplane bus. Comprehensive channel‑level diagnostics detect short‑circuit and overload conditions for fast troubleshooting inside pulp‑and‑paper, power‑plant heavy‑EMI cabinets. Model‑02 defines hardware variant, replacement spare must match full part‑number.

This module solves discrete‑control challenges: high‑density 16‑DO rack‑mount I/O, channel‑wise fault diagnostics, drop‑in spare compatibility for legacy Metso‑DNA retrofit‑maintenance projects. Process‑automation engineers, pulp‑paper & power‑plant maintenance technicians and retrofit integrators benefit most. Typical applications: paper‑machine auxiliary interlocks, power‑plant valve & motor control cabinets.

Key Application Notes

‑Rack‑mount I/O module; cannot operate standalone. Requires Metso DNA base rack, ACN‑C20 controller and DNA engineering software. ‑‑Model‑02 suffix defines hardware version; cross‑model substitution not allowed. ‑‑Not hot‑swap capable: rack 24 VDC power must be cut off before module replacement. ‑‑Original OEM production discontinued; only aftermarket surplus/refurbished spare available. ‑‑Conformal‑coated variant (‑CC suffix) available for high‑humidity / corrosive cabinet environments. ‑‑Origin: Finland; follow Metso DNA BOU83 hardware manual for field‑wiring and load‑current derating rules.
