Function

Multi-type input support: Supports thermocouple, RTD and millivolt signals, compatible with multiple sensor types, and adaptable to a wide range of temperature monitoring requirements.

High-precision measurement: 14-bit resolution, providing accurate temperature and analog signal data acquisition.

Diagnostic function: Built-in open-circuit detection (upward reading or default maximum value in RTD and thermocouple modes).

Open-circuit detection time: 2 scans (approximately 2 seconds).

Cold junction compensation: Supports cold junction compensation (CJC), which is achieved through terminals 37, 38, 39 and 46, 47, 48 to ensure the accuracy of thermocouple measurements.

Modular design: Supports hot plugging. Modules can be installed or removed while powered on, simplifying maintenance.

Compatible with multiple terminal bases, it is convenient for wiring.

Communication compatibility: Connect to ControlNet, DeviceNet or EtherNet/IP networks via Flex I/O adapters.

Status indication: Equipped with LED indicator lights, it shows the power status of the module and input faults, facilitating quick diagnosis.

Application scenarios

Industrial automation: Used in manufacturing, packaging and material handling systems to monitor equipment temperature and analog signals, such as conveyor belt and robot control.

Process control: Applicable to the chemical, oil and gas, and water treatment industries, it accurately measures process temperature to ensure process stability.

Distributed control system: In conjunction with the Flex I/O system, it is suitable for distributed I/O architectures, such as automotive production lines and food and beverage processing.

Temperature monitoring: Used in scenarios that require high-precision temperature measurement, such as HVAC systems, heat treatment equipment, and cold chain management.

Harsh environments: Its robust design and wide temperature range make it suitable for harsh environments such as mining and Marine engineering.
