NA300HCM301-0801 Single Channel Wiring Schematic
Note: Taking the nth channel (the value range of n is 1 to 8) as an example, when the
input signal is 24V, the positive terminal of the input signal is input to the terminal. Sub
Sn_A, the negative terminal is connected to the terminal Sn-; when the input signal is
5V, the positive terminal of the input signal is input to the terminal Sn_B, and the other
terminal is connected to Terminal Sn-.
