TYPICAL APPLICATIONS • Interlocked Guards, Light Curtains, Laser Scanners, Safety Mats 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. |
