NA300 Series Programmable Logic Controller Technical Specifications and User Manual
The current signal is converted into a digital signal by current-voltage conversion,
filtering, and A/D. After photoelectric isolation, the module's micro The processor reads
and then uploads to the controller master via the high-speed internal bus.
Terminal wiring diagram
The AIM301-1602 analog input module is wired with external devices through the
wiring terminals on the front of the module. The system is shown in the figure below,
and please note the following:
1.Each AI signal in the field is connected to the terminal with two wires (shielded
cable).
2.The input channel does not supply power to the transmitter, and the field 24V
needs to be used separately when connecting a two-wire transmitter. The DC power
supply powers the transmitter .
3. "01+", "01-" terminals are 1-channel analog input terminals; "16+", "16-"
terminals are16-channel analog input. Among them, the terminal "N+" (the value range
of N is 1~16) is connected to the positive pole of the analog input. Terminal "N-" is
connected to the negative pole of analog input (all "N-" are shorted internally).
4. All " NC" terminals are not used, wiri ng is prohibited.
