6EP1931-2EC21 SIEMENS SITOP DC UPS Module 15A, 24V DC
The SIEMENS 6EP1931-2EC21 SITOP DC UPS module is a high-performance uninterruptible power supply module designed to prevent costly system downtime, data loss, and production interruptions in 24V DC industrial control networks. Operating in conjunction with connected 24V external battery modules, this 15A DC UPS module bridges power failures by seamlessly supplying backup power to PLCs, industrial PCs, sensors, and actuators. It features DIP switches for customizable buffering times and battery threshold settings, integrated status LEDs, floating relay contact signal outputs, and a 9-pin RS-232 serial interface for system communication and controlled IPC shutdown. Built for standard DIN-rail mounting, it ensures maximum process reliability across automated manufacturing and process plants.
