Function

Thermocouple input processing

Supports 2 differential and isolated thermocouple input channels, compatible with multiple thermocouple types, and the measurement range covers -200°C to +2315°C.

The analog signal is converted to a 15-bit signed integer through the Delta-Sigma converter, with a resolution of 2.5 µV/ count.

Temperature unit support: Supports 4 temperature units (Celsius, Fahrenheit, Kelvin, Rand) and 1 custom mV unit.

Diagnostic function:

It provides channel-level diagnosis, including under-range, over-range, cold junction compensation (CJC), open circuit detection, open circuit detection, and high/high, low/low low alarms.

Diagnostic data is embedded in 8-byte scanner data (Rx) without consuming output data (Tx).

Flexible configuration

Support the configuration of thermocouple type, temperature unit, alarm threshold and cold junction compensation through software (such as Studio 5000 Logix Designer).

Provide channel-level engineering unit scaling and calibration modes.

Modular design

Compatible with POINT I/O communication adapters (such as 1734-AENT, 1734-ADN), and supporting distributed I/O architecture.

Detachable terminal blocks (RTB) simplify wiring and maintenance.

Compact and efficient

Compact in size, it is suitable for control cabinets with limited space.

Low power consumption design (1.0W) reduces energy consumption.

Status monitoring: Equipped with status indicator lights for modules, networks and input channels, it facilitates real-time monitoring and fault diagnosis.

No calibration required: Factory-calibrated, no additional calibration is needed, simplifying installation and maintenance.

Application scenarios

Industrial automation: It is used in PLC or PAC systems to monitor temperature signals in high or low temperature environments, and is suitable for factory production lines and equipment status monitoring.

Process control: In industries such as chemical engineering, oil and gas, pharmaceuticals, and metallurgy, precisely measure process temperatures (such as reactors, furnaces, and pipelines).

Manufacturing industry: In industries such as automotive manufacturing, food and beverage, and semiconductor production, monitor the temperature of processes or equipment to ensure production quality.

Distributed I/O system: In large factories, combined with POINT I/O communication adapters, it reduces wiring costs and enhances system flexibility.

High-temperature environment monitoring: Due to its support for multiple types of thermocouples, it is suitable for high-temperature applications such as steelmaking, glass manufacturing or heat treatment furnaces.

Equipment condition monitoring: It is used for predictive maintenance to monitor the temperature changes of motors, transformers or other equipment and prevent faults.

Space-constrained environments: The compact design is suitable for installation on small control cabinets or DIN rails close to on-site equipment.
