Omron G9SE Safety Relay Unit
Omron G9SE Safety Relay Unit
- A safety relay unit, often simply referred to as a safety relay, is a specialized electrical relay designed to ensure the safe operation of machinery and equipment. These relays are a critical component of safety systems in industrial and manufacturing settings. Safety relays are used to monitor and control safety-critical functions, such as emergency stops, door interlocks, light curtains, and other safety devices. They are responsible for ensuring that these safety mechanisms are functioning correctly and that they respond appropriately in hazardous situations to protect workers and prevent accidents.
