Safety relay mounts into PLC rack

Safety is an issue of paramount importance for today's manufacturer which cannot be ignored. Yet tight margins, lost time and rising costs remain high on the agenda. A common cause of costly operational downtime can be traced to the operation and resetting of traditional stand alone safety circuits.

Mitsubishi's innovative approach to safety relays closely integrates the stand alone protection and performance of safety circuits and the diagnostic capability of the PLC either by incorporation of the new QS safety relay onto the PLC rack, or by direct high speed CC-Link for the stand alone networked version. This configuration means that for the first time, detailed intelligence is instantly available on the operational condition of the safety relay as well as the status of each of the connected safety circuits, thereby allowing rapid identification of safety conditions on the plant.

“This is a major step forward for plant owners and machine operators,” says Jeremy Shinton, Q Series Product Manager for Mitsubishi Electric.
