Function

High-precision data acquisition: 16-21 bit resolution ensures accurate signal conversion, suitable for temperature, pressure, flow and other measurements.

HART protocol support: Each channel is equipped with an independent HART modem, supporting direct integration of HART devices, providing device diagnosis, configuration and real-time data.

Flexible data format: Supports three data formats, facilitating selection based on application requirements.

Module filter: Module-level filters reduce input signal noise, and the filtering frequency is adjustable.

Real-time Sampling (RTS): Configurable sampling frequency, the module periodically scans all channels and multicast data.

Over-range/under-range detection: When the detection signal exceeds the input range, it provides status indication to ensure measurement accuracy.

Disconnection detection: Detect the signal line being disconnected or the terminal block being removed (in 4-20mA mode).

Digital filter: Each channel can be independently set with a digital filter to smooth out the noise of the input data.

Application scenarios

Process control: Applicable to industries such as petrochemicals, pharmaceuticals, and food and beverages, it is used to monitor analog signals such as pressure, flow, and liquid level.

Equipment diagnosis: Obtain equipment status and diagnostic information through the HART protocol to optimize maintenance and troubleshooting.

Industrial automation: Used in factory automated production lines, it integrates sensors and transmitters to ensure high-precision data acquisition.

Energy management: Applied in the power, water treatment, and oil and gas industries, it monitors key process parameters.

Environmental monitoring: Used in environmental control systems to collect analog signals such as temperature and humidity.
