ABB 1SVR760740R0120 Temperature Monitoring Relay - Modbus RTU
Part Number: 1SVR760740R0120
Quick Summary
ABB 1SVR760740R0120 Temperature Monitoring Relay is designed to monitor process temperatures in industrial automation and control panels. Too many installations rely on separate sensors and external interfaces, creating wiring complexity and downtime during faults or calibration. The unit carries CE, UKCA, and UL/CSA certifications with RoHS and REACH declarations, simplifying global compliance and audits. With support for up to three sensor circuits using PT100, PT1000, PTC, NTC or a bimetal switch, it adapts to diverse industrial environments. Its Modbus RTU interface, front LCD, and Easy Connect push-in terminals accelerate commissioning, while the ABB EPiC app enables configuration even when unpowered. This combination delivers faster time-to-start, reduced wiring errors, and lower total cost of ownership for machine builders and panel shops.
Product Information
Extended Description
1SVR760740R0120 ABB: The CM-TCN.012P is an innovative temperature monitoring relay from the CM temperature monitors range.

FAQs
Mount the unit on a TH35 DIN rail (TH35-15 or TH35-7.5) and use the screwless terminals to connect conductors. Wire flexible or rigid 0.5–1.5 mm² conductors, following the 8 mm stripping length guideline. Ensure correct polarity for the supply and sensor inputs, and verify connections with a quick continuity check prior to power-up.
