Pathway eDIN Contact Closure interface provides twelve DMX-controlled dry contact closures for both power and signal level switching. Multiple operating modes include momentary, maintained, 6-channel split and single channel select, where the DMX level of the start channel determines which relay is active. The eDIN #1003 provides DMX512 control over twelve form-C relays, for signal level switching, in a DIN-rail mountable format. Each relay may be independently wired for normally-open (NO) or normally closed (NC) operation.
