Safety Relays are devices that implement safety functions



Safety Relays are devices that implement safety functions. In the event of a hazard, a safety relay must work to reduce risk to an acceptable level. The safety relay must initiate a safe and reliable response as well as monitor the integrity of its function. Safety relays are becoming a popular component in safety systems, due to increasing regulations and attempts to safeguard operators from hazards. When applied correctly, safety relays will detect failures in output and input devices, as well as internal failures, allowing power to be removed from a load, even if a contact is welded, and prohibit a subsequent restart of the load until the failure is corrected. Safety relays are just one component in the safety control system. All components in the system must be chosen and applied correctly, to achieve the desired level of operator safeguarding 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.
