Initial Air Gap: 0

Shield termination integrity depends on proper mating at both 40-pin connectors and cabinet grounding reference points

Using signals outside this range may compromise accuracy and safety

and input fuse protection

The cable construction supports stable signal propagation under cabinet-level electromagnetic noise conditions typical of densely populated DCS racks

Relay Board Module | Yokogawa ARM55D-000 RackInterface Initial Air Gap: 0Yokogawa ARM55D 000 Relay Board Module Configured for discrete dry contact signal distribution in CENTUM VP I O architecture, the Yokogawa ARM55D 000 (ARM55D 000 Relay Board) provides direct physical electrical execution of 32 point mechanical relay switching within Yokogawa field I O racks. The module interfaces downstream digital output channels to field devices via isolated dry contact relays, converting low level control signals into galvanically
