It is widely used in semiconductor, photovoltaic, petrochemical, ceramics, metallurgy, petrochemical and heat treatment industries.

Main features:

1 Adopts an advanced ARM processor for fast processing; the interface components are simple and reliability and stability are high.

2 It covers signals such as thermocouples of various common graduation numbers, RTDs, standard voltages and standard currents; the fast and accurate nonlinear correction algorithm ensures the accuracy of digital sampling.

3 Unique PV measurement and control process memory function, with up to 1024 points of measurement and control process memory data. The memory interval is adjustable from 1 to 60 seconds. Users can quickly browse the data with a single key operation, and the memory data is automatically refreshed according to the browsing time requirement.

4 Abundant alarm outputs, with 4 alarm registers that can be freely combined.

5 Standard analog transmitter output function; the transmitter data source, transmitter type and transmitter range are freely configurable.

6 Dual-row 4-digit digital tube display; the human-machine interaction is simple and easy to use.

7 Plug-and-play modular structure and abundant output specifications, suitable for various application needs.

8 Adopts the standard MODBUS communication protocol, with strong universality and high reliability.

9 Strong anti-interference performance; meets the requirements of industrial level 3 electromagnetic compatibility testing.
