Schneider Electric Telemecanique XPSFB3711 Safety Relay

Schneider Electric Telemecanique XPSFB3711 is a dual-channel safety relay that provides emergency stop and safety interlock monitoring for industrial automation, delivering reliable shutdown and restart control in packaging machines, conveyor systems, robotic cells, and other production equipment. Part of the Preventa XPSFB family, it mounts to a DIN rail, operates at 230 V AC, uses screw-terminal connections, and provides three safety contacts with a rated current of 2.5 A to supervise critical safety outputs. The module processes safety inputs and drives multiple safety outputs to ensure safe operation of industrial machinery, making it a common choice for emergency stop circuits and safety interlocks across conveyor installations and machine guarding applications. Common replacements include XPSAC3721, XPSAF5130, and XPSAR371144.
