SR-2H

Two Hand Safety Relay

Compact DIN rail mounted safety relay. Low profile for tight spaces.

SAFE and CONTROL RELIABLE

The SR-2H safety module monitors two buttons with mechanical NO-NC contacts or complimentary sourcing transistor outputs. The module provides two monitored, redundant, forced-guided outputs which close when both palm buttons are activated within 0.5 seconds of each other.  If the machine operator removes one or both hands from the actuating device(s), the module relays de-energize, causing the output contacts to open. The relays will not re-energize until both actuating devices are deactivated and then simultaneously reactivated.
