The Pilz PNOZ c1 24VDC (part number 710001) is a standalone safety relay from Pilz's PNOZcompact series. Its primary function is to monitor safety devices on industrial machinery, such as E-STOP pushbuttons and safety gates (interlock switches), to protect personnel from hazardous machinery movements.
When a safety device is activated (e.g., an E-STOP button is pressed), the safety relay immediately opens its safety contacts to remove power from the machine's control circuit, halting dangerous motion.
