Safety Relays are devices that implement safety functions. In the event of a hazard, a safety relay will work to reduce to risk to an acceptable level. When an error occurs, the safety relay will initiate a safe and reliable response.
Each safety relay monitors a specific function. By connecting them to other safety relays, one can achieve total monitoring of a machine or plant. Safety relays are a simple and efficient way to meet existing safety standards, resulting in safe operation for your personnel and equipment as well as a long service life.
Risk reduction should be a priority for any business, to both protect its employees and reduce the possibility of costly accidents or equipment replacement.
Generally, if a risk is able to be reduced, then it should be.
Some functions of safety relays include:
- Stopping a movement in a controlled and safe manner.
- Monitoring the position of movable guards.
- Interrupting a closing movement during access.
- Emergency off/stop.
