Product Brief:​ Monitors up to two independent strings of PTC thermistors (DIN 44081/44082) embedded in motors, dry-type transformers, or bearings. If any PTC resistance exceeds the trip threshold (> 1,800 Ω typical, switching point < 4,000 Ω) the relay drops out and triggers alarm/shutdown. Includes power-on delay to suppress nuisance tripping when supply is applied (transformer secondary used as supply). Two independently configurable changeover relays for pre-alarm and trip/off functions.
