For Use With
Machine Control
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-954-1f, 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.
