1. Signal input, user can choose arbitrarily. (Thermocouple, RTD, Voltage, Current, Linear Resistance, Frequency).

2. Single-screen or dual-screen LED display. The range display can be arbitrarily corrected according to the working conditions. The linear input signal display range can be set arbitrarily, and it can also be displayed as a square root, and the small signal can be removed.

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

4. It can provide 2 to 4 relays for d.u independent output, and 4 relays can also be related to output in pairs, and the alarm control mode can be selected arbitrarily. It can realize the fault alarm output of the input terminal.

5. It can realize timing or counting function, and can also count reversibly.

6. It can be used as a current and voltage giver. If there is no input signal, the displayed content can be changed to the percentage of process quantity and control quantity by pressing the key.

7. 24V power supply can be supplied externally (provided to the two-wire transmitter).

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

9. It can provide multi-host, single-host, and no-host RS485 asynchronous serial communication mode. Communication data verification follows the CRC-16 American data communication standard, high reliability cycle, and barcode verification.
