How do Safety Relays work and what are they used for?

Safety Relays work by helping reduce unnecessary risk and hazard within your circuit. A typical circuit configuration may look like a production line where highly automated machinery works quickly, i.e. a production or packing line in a warehouse or factory. This line forms part of your 'circuit' and along that circuit you will have safety devices in place like emergency push buttons, safety curtains or pressure sensitive mats. To ensure complete safety in these environments, a safety relay can be added to your circuit to allow you full control and monitoring of your working environment. A safety relay will run regular checks down your circuit by sending pulses back and forth to confirm whether any (for example) wiring was implemented incorrectly or any welding has occurred along the circuit. Once the relay has detected this, it would then shut down the area by cutting off the power, until the fault can be determined and fixed. Most recent safety relays feature intuitive LED displays that will alert users to any faults, this is of course useful to prevent harm to users and also proactively engage in maintenance before any machinery is damaged beyond repair, so certain cost savings can be associated when using a safety relay.

Some safety relays have specific functions and only work with certain devices like E-STOPs, some work better with other devices like safety curtains. More than one safety relay can be used to give you total monitoring of your circuit, ensuring you and your employees safety.

What are the differences between a traditional 'relay' and a 'safety relay'?

A traditional relay will open and close your circuit and the switch devices down that line, however it will not monitor it in the same way a safety relay will and cannot automatically shut down specified areas to prevent harm to the machinery or workers. Safety relays are not prone to same potential risks that traditional relays are and can be relied upon to monitor short circuit faults, ground faults or wire breakage. Offering a greater protection over their counterpart relays, they are specifically designed with your safety in mind.

How do you operate a Safety Relay?

You must first align and wire the safety relay into your line and follow the setup instructions provided (will vary per manufacturer). Follow the onscreen instructions of the LED parallel to your instructions to perform integration into your circuit line. Depending on what parameters you set will determine the function of the safety relay (i.e. you tell it to cut off certain areas after certain criteria have been met, or you opt for a circuit wide halt of the line).
