The Schmersal PSC1 series is a modular, freely programmable compact safety controller designed for safe signal processing of emergency stop devices, safety door monitoring systems, safety light grids, and other electronic and mechanical safety switching devices. It offers a flexible and scalable solution for machine safety applications, from small standalone machines to complex production lines.

Key Features

• High Safety Integrity: Certified up to PL e (EN ISO 13849-1), SIL 3 (IEC 61508), and Category 4, ensuring compliance with the highest safety standards for machinery.
• Modular Scalability: Base modules (PSC1-C-10 and PSC1-C-100) offer 14 safe inputs, 4 safe semiconductor outputs, 2 safe relay outputs, and 2 pulse outputs. The system can be expanded with up to 8 expansion modules, reaching a total of up to 272 safe inputs/outputs.
• Comprehensive Communication: Universal communication interface supports all standard fieldbus systems, including EtherNet/IP, PROFINET, EtherCAT, Modbus TCP, PROFIBUS, and CANopen. Integrated OPC UA server enables seamless IIoT integration.
• Integrated Safe Drive Monitoring (SDM): Compliant with EN 61800-5-2, the PSC1 can safely monitor up to 12 axes with functions including Safe Torque Off (STO), Safe Stop 1/2 (SS1/SS2), Safe Limited Speed (SLS), Safe Direction (SDI), Safe Speed Monitoring (SSM), and Safely-Limited Increment (SLI).
• Flexible I/O Configuration: Safe outputs on expansion modules can be easily reprogrammed as safe inputs, allowing adaptation to specific application requirements. Semiconductor outputs can be configured as p-switching or p-/n-switching.
• Efficient Programming & Diagnostics: Function-plan-oriented programming using intuitive software. Offline simulation, extensive diagnostic options, and a 7-segment display with I/O status LEDs simplify setup and troubleshooting.
• Secure Data Handling: Memory card options allow for quick programming of identical systems and secure storage of application data.
