Power Supply Safety Bumper Control Interface (RKR164) –
The safety bumper control interface (Part No. RKR164) consists of a safety controller, power supply, force-guided relays, terminals, and fuses all inside an enclosure for bumper switches. An on/off selector switch and a lighted reset push button are on the front of the enclosure. If the safety bumper is pressed and stops machine motion, then the reset button must be pushed to allow a restart of the machine. Connection of the safety bumper and interface provides a Category 3 safety system when properly integrated with the existing control system.
