1. Signal input, user can choose freely. (Thermocouple, thermistor, voltage, current, linear resistance, frequency).

2. Single or dual screen LED display. The range display can be adjusted arbitrarily according to the working conditions. The linear input signal display range can be set arbitrarily, and can also be displayed as a square root, with a small signal cut off.

3. The secondary screen can switch between set values and output values.

4. It can provide 2-4 relay outputs, and 4 relays can also be associated with each other for output. The alarm control mode can be freely selected. Can achieve input fault alarm output.

5. It can achieve timing or counting functions, as well as reversible counting.

6. Can be used as a current and voltage setter. There is no input signal, and the displayed content can be changed to the percentage of process quantity and control quantity through buttons.

7. Can provide external 24V power supply (for two wire transmitters).

8. Measurement value transmission output: 0-10mA, 4-20mA, 0-5V, 1-5V, 0-10V, etc. The transmission range can be set arbitrarily and corrected.

9. We can provide RS485 asynchronous serial communication with multiple hosts, single hosts, and no hosts. Communication data verification follows the CRC-16 American data communication standard, with high reliability cycling and barcode verification.
