1, signal input, user arbitrary choice. (Thermocouple, thermal resistance, voltage, current, linear resistance, frequency).

2, the measurement value, set value can be displayed by analog bar, digital screen, display content can be switched freely.

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

4, 8 alarm control mode selection.

5, can be prescription and small signal excision.

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

7, the alarm relay can choose the output state when there is a failure of breaking resistance, breaking couples and breaking lines.

8, can be a counter and reversible counter instrument, after the power failure to restore the power before the count value, can clear the count value, can be preset number, can be the count value of the upper and lower limits of alarm and output.

9, can realize the associated alarm control mode.

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

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

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