ABB NRAI01 is a Bailey legacy rail-mounted input termination unit used to land field input wiring and route the signals through a matching termination cable to compatible INFI 90 or Network 90 input hardware.
ABB NRAI01 is a Bailey legacy rail-mounted input termination unit used to land field input wiring and route the signals through a matching termination cable to compatible INFI 90 or Network 90 input hardware.
NRAI01 provides the physical field-input termination and cable interface in an installed Bailey control system. It does not perform the controller logic or analog conversion, so the associated input module, cable and channel drawing must match.
Confirm the complete NRAI01 marking and revision, rail assembly, connector keying, field signal type, loop-power arrangement, termination cable, associated input module, channel map and shield grounding before replacement.
