1. Signal input, users can choose freely. (Thermocouple, Thermistor, Voltage, Current, Linear Resistance, Frequency).   

2. Single screen or dual screen LED display. The range display can be adjusted arbitrarily according to the working conditions. The display range of linear input signals can be set arbitrarily, and square root display can also be used, with small signal cutoff added.  

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

4. It can provide 2-4 relays with direct output, 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, and can also count reversibly.  

6. Can be used as a current and voltage setter. No input signal, the displayed content can be changed to the percentage of process quantity and control quantity by pressing the button.  

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 host, and no host modes. Communication data verification follows the CRC-16 American data communication standard, with high reliability cycling and barcode verification.
