The input specification of each port is as follows.

 

l Input port component: AC input photocoupler

l Input impedance= 3 ㏀

l (+) Common input voltage = 24 VDC

l (-) Common input voltage = 0 VDC

 

The user connects the input signal through the method shown in Figure 5.13 below. First, connect the user power +24 V and ground wire to the public IO board (BD582), and then connect each signal to the input pin, depending on the usage. The power can be differently used by the 8 input port units.
