The UE45-3S1 safety relay monitors safety switches and emergency stop pushbuttons in applications with a safety brake.
It offers 2 safety contacts, which directly switch off some of the actuators. The other actuators must be active until the machine has come to a complete stop. These actuators can be deactivated after a certain time.
This ensures the brake stops the machine, allowing access once the machine has come to a complete stop.
