Specification of Pnoz X3 Safety Relay
Safety Relays, Therefore, Are Devices Which Generally Implement Safety Functions. In The Event Of A Hazard, The Task Of Such A Safety Function Is To Use Appropriate Measures To Reduce The Existing Risk To An Acceptable Level. These May Be Safety Functions Such As:[5] [6]
- Stop A Movement In A Controlled And Therefore Safe Manner
- Monitor The Position Of Movable Guards
- Interrupt A Closing Movement During Access
Safety Relays Monitor A Specific Function; By Connecting Them To Other Safety Relays They Guarantee Total Monitoring Of A Plant Or Machine. The First Safety-Related Control System Ultimately Came From The Desire To Connect Functions Flexibly Through Programming, Similar To The Way This Is Done On A Programmable Logic Controller (Plc).[7] [8] [9]
