I/O Relay Module Racks
Products in this family are interconnect devices used to create an interface between one or more I/O relay modules and an installation's fixed wiring in order to ease replacement of worn or damaged relays, and/or to incorporate such relays at the juncture between a control signal bus and field wiring. They are used primarily to provide isolation when connecting devices powered from different sources and operating at different potentials to a common control system in an industrial environment.
