PLC safety relay

By Control Engineering Staff December 1, 1999

North Andover, Mass. -Schneider Electric has introduced two new safety relay modules for the mid-range Premium PLC platform. The safety modules are used to interrupt one or more emergency stops, safety stop control circuits, or provide electrical monitoring of limit switches activated by protection devices. These complete safety systems satisfy the European machine directive for emergency stops (EN418) and EN60204-1 for safety circuits with Level 4 safety. The modules accommodate up to 12 double-contact push buttons or limit switches with 2 or 4 immediate stop safety outputs. The Premium safety module also provide users with space saving benefits, reduced wiring, and the ability to enable safety status data to be easily integrated over the Premium backplane for monitoring. The safety relays are completely independent of the Premium PLC.
