Function of 4 20 mA Controller ZHC4661
The signal current of general instruments is 4-20mA, which means that the minimum current is 4mA and the maximum current is 20mA. When transmitting a signal, consider that there is also resistance on the wire. If voltage transmission is used, a certain voltage drop will be generated on the wire, and a certain error will occur in the signal at the receiving end. Therefore, the current signal is generally used as the standard transmission of the transmitter.
ZHC4661 is a remote control product that supports analog follow and control acquisition.
Support 4 analog inputs, default current detection.
Support 2 analog output, default current output.
Support analog follow and control acquisition.
AO Output Calibration
ZHC4661 provides an AO reference voltage adjustment interface. The reference voltage has a positive relationship with the output signal. When the actual output signal is lower than the ideal output signal, increase the reference voltage; when the actual output signal is higher than the ideal output signal, reduce the reference voltage. Unit: mV
