6. ANALOG INPUT MODULE (AAD04A) CONNECTIONS B-61813E/03
6.3 CONNECTING WITH ANALOG INPUT MODULE
1 Though the example above shows the connection of
channels 0 and 2, it is just the same with the cahnnel
1 (I1+, V1+, V1-, COM1 and FG1) and the channel 3
(I3+, V3+, V3-, COM3 and FG3).
2 Either voltage input or current input can be specified
for each channel. When current input is specified,
make sure to short-circuit in + and Vn+.
3 Use shielded cables of twisted pair for connecting.
4 Connect the COMX (X: 0 to 3) terminals to the input
voltage and current source common (GND) points to
fix the ground potential of the conversion section in
the module at the ground potential of the input power
The VX- (X: 0 to 3) and COMX (X: 0 to 3) terminals
may have to be strapped depending on the
specifications of the input voltage and current
sources (if the voltage source external outputs, OUT-
and GND, are common).
