PSSU safety controllers have redundant safety output relays, are self-monitoring, and are rated Control Reliable, which means that any fault in the safety-critical components will be detected and the machine will be rendered inoperative until the fault is corrected.
These safety controllers are designed to be used with Tapeswitch low-voltage sensors such as ribbon switches, safety mats, sensing edges, or sensing bumpers. PSSU safety interface modules are available in wall-mounted and DIN rail-mounted versions. Other options include 24 Vdc or 110/220 Vac operation and choice of manual or auto reset.
