Product Description
It acts as field‑wiring interface for dry‑contact / wet‑contact discrete input signals from site switches and relays. It routes field status signals via screw terminal blocks and on‑board signal‑conditioning circuits to main Mark VI controller boards through internal IDC ribbon connectors. It is a passive interface board without processing capability. Available supplies are new surplus stock and fully‑tested refurbished units. No drop‑in replacement; same‑part‑number replacement is required for maintenance.
