Safety relays

Safety relay ESR4 for monitoring of the safety circuits

The electronic safety relays ESR4... are an important component of the safety equipment.

In fault-free operation, the safety-relevant circuits are monitored by the electronics after the switch on command and the enable paths are enabled via the relay.

The enable paths are interrupted immediately or after a time-delay - depending on the application - when the switch-off command is received, as well as during a fault with an earth fault, short-circuit or wire breakage. The devices are designed with redundant features and offer safety for personnel and machines.

You can choose between the following safety relays:

• Emergency-Stop
• Protective door
• Light barrier
• Two-hand control
• Off delay and
• Contact extension.
