Epec SC52 Safety Control Unit


Epec SC52 is a state-of-the-art controller for safety-related systems in mobile machinery. Outputs in SC52 have a high-side current measurement, so only one I/O pin is needed to control proportional valves.

SC52 offers a flexible solution for software-based safety function implementation. Together with the SC52 controller, Epec offers a set of pre-certified PLCopen application libraries in order to reduce customer’s safety related software development effort.
