PRODUCT DESCRIPTION
SIEMENS 3RS2500-1AA30 - Temperature Monitoring Relay
The SIEMENS 3RS2500-1AA30 is a SIRIUS 3RS2 series temperature monitoring relay engineered for precise thermal oversight in industrial environments. This device provides reliable protection and control by monitoring a single Pt100/Pt1000 sensor input and activating a potential-free changeover contact upon exceeding or falling below user-defined temperature thresholds. It is designed for integration into motor control centers, process automation systems, and machinery requiring critical temperature supervision.
