TYPICAL APPLICATIONS
-Interlocked Guards
-Machine Input/Output Signals
A safety relay is designed to connect safety devices, such as interlock switches, to the machine control circuit. It provides a switching action from the safety interlock switch, and can act as an intermediate relay to distribute a signal to multiple devices. The relay compares input and output signals, and provides failure to a safe condition if there is a failure in the interlocking interface control circuit.
Without a safety relay, faults and short circuits in a safety interlock switch can go undetected and can create a hazardous situation. The potential for faults exists in the power supply, relays, and switches as well as their associated wiring.
When using a safety relay, the wiring is monitored and compared. If a failure occurs in one area, it will be detected and a stop signal will be sent to the safeguarded machine.
This dual-channel safety relay has 1 NC or 2 NC dual-channel safety inputs. It is designed for use with guard interlock switches or a light curtain.
This safety relay has 3 NO safety outputs and 1 NC auxiliary output. The safety outputs have independent and redundant internal contacts to help the safety function. The auxiliary contact is a nonsafety output intended to provide an external signal about the status of the safety outputs.
