Phoenix PSR-M Series: Modular Safety Gateways & Extension Modules - Selection Guide
Product Overview
The Phoenix PSR-M Series is a modular safety system consisting of safety gateways, encoder extension modules, and functional I/O modules, designed for industrial safety automation. Supporting multiple industrial bus protocols (PROFINET, PROFIBUS, Modbus TCP, EtherCAT, CC-Link), encoder signal integration (SINCOS/HTL/TTL), and safety I/O expansion (digital/analog), these modules enable seamless integration of safety circuits with control systems. Compliant with global safety standards (SIL 3, EN ISO 13849-1 PLe), they offer two terminal options (screw/SC, plug-in/PI) and 35mm DIN rail mounting. Ideal for machine tools, conveyors, and production lines, they provide reliable safety control, signal feedback, and bus communication in critical industrial scenarios.
