The PSSU series of safety controllers can be used as safety devices for high-risk automation and machine control applications. They provide the highest level of safety offered by Tapeswitch, exceeding the requirements of safety category 3 as defined by EN-954-1, and meeting or exceeding the safety content of the applicable OSHA, ANSI, and RIA Standards for safety interface modules.

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.
