Low-Maintenance Terminal Blocks Carry Initiator, Actuator Signals

With a mounting base designed to accommodate eight 45-mm wide or 16 to 17, 90-mm wide I/O points, these terminal blocks address the increasing complexity of process control wiring. The base module has room for a power supply terminal that uses the integrated bus bar to distribute excitation/supply voltage to adjacent I/O points, eliminating the need for a bridging accessory item. The mounting base can be either DIN rail or panel mounted. A sensor block package allows users to disconnect a single terminal or I/O point without having to interrupt the power supply. This feature makes maintenance easier. LED versions allow remote checking of switch status without instruments.
