E-Stop Safety Relays Monitor Switch Circuits

Useful for monitoring normally-closed E-stop switch circuits and safety gates for contact failure or wiring faults, this selection of devices includes: dual-channel relays in 22.5 and 45 mm widths for Safety Category 4 applications; one-channel, 22.5-mm E-stop relay modules for Safety Category 2 uses; and 22.5-mm safety device extension modules with or without delay times for Category 0 and Category 1 stop applications. All models have DIN rail-mountable enclosures. Output response is 20 to 30 ms, and the relays include automatic reset or manual reset and LED indicators for power and output status.
