How to Use Safety Relays to Monitor Safety Mats? Wiring Diagrams and Applications
A safety mat is a presence-sensing safety device (PSSD) containing internal pressure switches. When a person steps onto the mat, these switches close; when the person leaves, the switches open, thereby generating an on-off signal that is sent to a safety relay. Together, the safety mat and the safety relay form part of a safety system designed to detect presence in a hazardous area.
