SCR-3: Safety Monitoring Relay
The SCR-3 is an all purpose Safety Monitoring Relay that ensures the quick and safe deactivation of the moving parts of a machine in case of danger.
Applications include single and dual channel emergency stop circuits or dual channel safety guard monitoring using Tongue Switches or Non Contact Switches.
The internal logic system closes the relay safety outputs when the start button is pressed.
If the control lines are opened by operation of a Safety Switch or E Stop button then the safety output contacts are opened and safely switch off the supply to the machine. It is ensured that single fault does not lead to the loss of the safety function and cyclic monitoring means that any fault is detected no later than the next start up.
