Pilz Pnoz V 30S 3S 1Sz/1O Relay 474790

Buy Pilz Pnoz V 30S 3S 1Sz/1O Relay 474790

Selected by motion safety specialists, the Pilz Pnoz V 30S 3S 1Sz/1O Relay 474790 handles both electromechanical and solid-state switching from one compact module. Three safety contacts manage conventional loads while the semiconductor output handles electronic devices requiring bounce-free switching. The auxiliary contact feeds diagnostic data to maintenance systems, and adjustable velocity thresholds cover everything from slow agitators to high-speed spindles without requiring multiple relay variants.
