1. Signal input is optional for users. (Thermocouple, thermal resistance, voltage, current, linear resistance, frequency).

2, the measured value, set value can be used for analog bar, digital screen display, display content can be freely switched.

3, the measured value and the set value can be added or subtracted operation.

4, 8 kinds of alarm control mode selection.

5. Prescription and small signal excision can be performed.

6, switching power supply type instrument can have 5 switching output, one for the input part of the disconnection alarm, the other 4 for the bit control.

7. The alarm relay can choose the output state when the fault occurs.

8, can be used as a counter and reversible counter meter, power off after the restoration of the power before the count, can clear the count, preset number, can be on the count of the upper and lower limits of alarm and transmission output.

9, can realize the associated alarm control mode.

10, for external 24V, 30mA or 50mA or 100mA power supply (can be used as two line transmitter power supply).

11, the measured value or the given value of the output :0 ~ 10mA, 4 ~ 20mA, 0 ~ 5V, 1 ~ 5V, 0 ~ 10V.

12, can provide multi-host, single host, no host RS485 asynchronous serial communication mode. Communication data check is in accordance with CRC-16 American data communication standard, high reliability cycle, bar code check.
