Function

RTD input processing

Supports 2 single-ended, non-isolated channels, compatible with 100 Pt α = 0.00385 Euro RTD sensor (-50... +320 °C / -58... +608 °F and 0-220 Ω resistance signal.

The analog signal is converted to a 16-bit signed integer through the Delta-Sigma converter to provide high-resolution temperature or resistance measurement (2.4 mΩ/ count, 0.006 °C/ count).

High resolution

Compared with 1734-IR2, 1734-IR2E offers higher resolution and is suitable for higher-precision temperature measurement applications.

Diagnostic function:

Provide channel-level diagnosis, including over-range/under-range, ultra-high/high/low/ultra-low alarms and open circuit detection.

Diagnostic data is stored in 16-bit registers and can be used for local monitoring or integrated into HMI, SCADA or DCS systems.

Flexible configuration

Supports multiple temperature units and user-defined units (mV).

Channel parameters can be independently configured, including sensor type, temperature unit, engineering unit scaling, and alarm threshold.

Modular design

Compatible with POINT I/O communication adapters and supporting distributed I/O architectures.

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 external power supply required: No additional DC power supply is needed, simplifying system design.

Application scenarios

Industrial automation: Used in PLC or PAC systems to monitor temperature or resistance signals, suitable for factory production lines and equipment status monitoring.

Process control: In industries such as chemical engineering, oil and gas, pharmaceuticals, and water treatment, it precisely measures temperature (such as in reactors, storage tanks, and pipelines) or resistance signals.

Manufacturing industry: In industries such as automotive manufacturing, food and beverage, and packaging machinery, monitor process temperatures 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-precision temperature monitoring: Due to its high resolution, it is suitable for applications that require precise temperature measurement, such as laboratory equipment or precision manufacturing.

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

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