ABB 1SVR750740R0120 Temp Monitoring Relay - LCD RTU
Part Number: 1SVR750740R0120
Quick Summary
ABB CM-TCN.012S temperature monitoring relay provides precise, multi-sensor temperature supervision for industrial equipment. Installing and configuring multiple sensors can be time-consuming, risking misconfiguration and downtime. Key capabilities include PT100, PT1000, PTC and NTC sensing, a front LCD, NFC access, and Modbus RTU communication, with configuration via the ABB EPiC app for quick commissioning. Certification details such as CE, SIL readiness, or IP ratings are not listed in the data; please verify with ABB for exact compliance. Used in production lines and automation control, this device reduces commissioning time, improves traceability, and supports scalable sensor monitoring in a compact package.
Product Information
Extended Description
1SVR750740R0120 ABB: The CM-TCN.012S is an innovative temperature monitoring relay from the CM temperature monitors range. This monitoring relay operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 3 c/o (SPDT) output with contacts rated at 250 V / 4 A. The CM-TCN.012S is able to measure temperatures with up to three sensor circuits using different type of sensors PT100, PT1000, PTC or NTC and it has embedded Modbus RTU communication interface. The LCD at the front of the relay shows the currently measured values and maintenance data. The CM-TCN.012S can be configured exactly as you need either via a black-lit LCD or smartphone app. Parametrization and configuration are just one touch away with the ABB EPiC app – even in a non-powered state – reducing installation time by 80%. The device offers screw connection technology with double-chamber cage connection terminals.

FAQs
The CM-TCN.012S supports 24-240 VAC/DC power and three SPDT outputs, with screw-terminal wiring for reliable field connections. It interfaces via Modbus RTU and can be programmed through the LCD panel or the ABB EPiC app, enabling quick integration with PLCs and existing automation architectures.
This device monitors up to three sensor circuits and supports PT100, PT1000, PTC, and NTC sensors. The multi-channel approach allows centralized monitoring for several temperature points, reducing the need for separate relays and simplifying sensor management.
Connect the CM-TCN.012S to the PLC via Modbus RTU on the front communication interface. Use the LCD or the ABB EPiC app to configure addresses and parameters, then map the 3 SPDT outputs to PLC inputs. This enables streamlined data exchange and remote diagnostics in standard automation projects.
Certification details such as CE, SIL readiness, or IP ratings are not listed in the provided data. Verify exact compliance and any region-specific approvals with ABB or your distributor before commencing a critical or regulated installation.
The EPiC app enables one-touch configuration, even without power, dramatically reducing commissioning time by up to 80%. Centralized multi-sensor monitoring improves maintenance efficiency, speeds fault identification, and lowers lifecycle costs by reducing field visits and simplifying spare parts management.
