AutomationDirect has added modular Z-Range safety switch system components to its portfolio of safety products. The Z-Range safety switch system offers modularity, allowing up to 30 Z-Range safety devices to be connected to one safety relay while maintaining PLe performance rating. These devices are rated for SIL3 and feature built-in local diagnostics. Available devices include non-contact safety switches, solenoid locking RFID tongue interlock safety switches, tongue interlock safety switches, hinge interlock safety switches, cable-pull safety switches, emergency stop control stations and Z-Range safety switch system accessories. Wiring is simplified with premade wires, T-cables and junction blocks.
