Monitoring Safety Relays
Minotaur MSR23M
Description
The MSR23M control unit is designed to monitor 4 wire safety mats
that are connected together to form a safeguarded zone. The size of
the safeguarded zone is limited by the total input impedance (100
ohms maximum) created by the wiring and connections. The
controller is designed to interface with the control circuit of the
machine and includes two safety relays to ensure control redundancy.
The controller detects a presence on the mat, a short circuit, or an
open circuit. Under each of these conditions, the safety output relays
turn off. When interfaced properly, the machine or hazardous
motion receives a stop signal, and an auxiliary output turns ON.
