The ESR5 electronic safety relays from the Eaton Moeller series™ provide reliable monitoring of safety installations such as emergency-stop buttons, safety doors, light curtains and controls, and will switch them to a safe operating state in the event of an emergency. Despite their narrow width, the safety relays meet the highest safety standards.
Up to performance level PL e according to EN ISO 13849-1
Up to safety integrity level SIL CL 3 according to IEC 62061
Up to 5 enabling-current paths and 2 signal-current paths
TÜV Rheinland, UL/CUL and CSA approvals
UC versions available
Safe monitoring of emergency-stop circuits
The internal logic of the safety relays monitors the safety circuits and activates the enabling-current paths if no faults are detected. The enabling-current paths will be switched off if the safety device has been actuated, or in the event of a fault.
Monitoring of movable guards
The monitoring of protective guards and doors is another important function. In addition to restart monitoring, the safety relays can also be used to implement automatic starts. This shortens the cycle times of production processes without compromising on safety.
ESR5 safety functions
The devices offer the following safety functions: emergency shutdown, the monitoring of movable guards, the monitoring of exposed hazardous areas, safe operation with two-hand control, delayed and instantaneous contact expansions, and shutdown with off delay.
