Safety Relays with Diagnostic Capabilities
 |  |
Relay | Relay with Time Delay |
Control and diagnose issues with safety-critical circuits. These relays have a microprocessor that monitors safety components, such as emergency stops and light curtains, and sends a signal to stop the operation if a failure is detected and restart when the issue is resolved. They also help with diagnostic tasks because of their feedback circuit, which allows basic relays to communicate their status back to the safety relay. These relays have a duplicate set of input and output signals, so they’ll still stop the controlled device if one of the inputs fails.
IP20 rated, they have recessed terminals which prevent fingers and other objects from touching live circuits. These relays have been tested to multiple safety standards and can help achieve PL, SIL, or CAT system ratings. They also meet ISO and IEC standards for machine safety.
Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.
Time Delay—Relays with delayed safety outputs are often used where power must be maintained after an input signal is received. For example, after a stop button for a machine is pressed, the guard door will stay locked until the machine cycle is finished.
