AutomationDirect: Schmersal PROTECT PSC1 Safety Controller
March 9, 2026
The Schmersal PROTECT PSC1 safety controller is a compact safety control system with scalable I/O from a trusted provider of machine safety.
E-stops, light grids, and almost any safety device can be monitored with ease, and the universal interface ensures instant connection to every standard fieldbus.
The base models, PSC1-C-10 and PSC1-C-100, include 14 safe inputs up to PL e or SIL 3, 4 adjustable safe semiconductor outputs, 2 safe relay outputs, and 2 pulse outputs. The PSC1-C-10 includes 2 signaling outputs, and the I/O can be expanded by adding up to 2 expansion modules. The PSC1-C-100 adds 6 signaling outputs and 20 adjustable safe I/O points. This more advanced model can be expanded by adding up to 8 expansion I/O modules. Both models have the option for built-in fieldbus support for EtherCAT, PROFINET, and EtherNet/IP or Modbus TCP, depending on the model selected, so no additional communications modules need to be purchased.
Schmersal PROTECT PSC1 safety controllers start at $777.00 (PSC1-C-10).
