Intelligent light column display regulator function
1. Universal signal input, user can choose arbitrarily. (Thermocouple, RTD, voltage, current, linear resistance, frequency).
2. The measured value and set value can be displayed by analog bar and digital screen, and the display content can be switched freely.
3. The measured value and the set value can be added or subtracted.
4, 8 kinds of alarm control mode selection.
5. Prescription and small signal resection can be performed.
6. The switching power supply type meter can have 5 switching outputs, one for the disconnection alarm of the input part and the other 4 for position control.
7. In the event of broken resistance, broken couple or broken wire, the alarm relay can choose the output state.
8. It can be used as a counter and a reversible counter instrument. After the power is turned off, the power is restored and the count value before the power is restored. The count value can be cleared, the number can be preset, and the count value can be alarmed and transmitted.
9, can achieve associated alarm control.
10, for external 24V, 30mA or 50mA or 100mA power supply (can be used as a two-wire transmitter power supply).
11. Measured value or internal given value transmission output: 0 ~ 10mA, 4 ~ 20mA, 0 ~ 5V, 1 ~ 5V, 0 ~ 10V.
12. RS485 asynchronous serial communication mode with multiple masters, single masters and no masters can be provided. The communication data verification complies with the CRC-16 American data communication standard, high reliability cycle, and bar code verification.
