Isolators

Curtiss-Wright Nuclear has a large line of isolators, preventing faults in non-safety equipment from affecting safety equipment. These isolators range from single-channel, field-mounted units intended to drive a non-safety indicator or alarm, to 19” rack modular systems designed to handle a large number of signals originating in safety systems and being monitored by the non-safety plant computer. All are fully tested and qualified.
