Section 2 - Installation
Isolated 4-20 mA Input
“B” Option Board Only.
This example
shows Analog Input 2 on a “B”
Option Board that is plugged into Slot 2. Turn
ON switch 1-2 to connect the internal 250.0-
ohm resistor.
The “-” of each channel is isolated from all
other channels and from the CPU Signal
Common “-”.
The External Power Su
pply “-” and the “B
Board “-” for this channel must be connected.
The shield connects to the External Power
Supply “-”.
1-5 Vdc Input
Typical for: CPU, “A”, and “F” boards.
This example shows Analog Input 4 on the CPU
Board. Remove JP 1-4 to disconnect the
internal 250.0-ohm resistor.
The 5-Mohm input impedance of each channel
allows over 15 PCC-IVs to be connected to the
same 1-5 V signal.
See “Pull-Up/Down Resistors” in this Section
The External Power Supply “-” and the PCC-IV
Signal Common “-” must be connected.
The shield connects to the External Power
Supply “-”.
0-10 Vdc Input
Typical for: CPU, “A”, and “F” boards.
This example shows Analog Input 5 on the
CPU Board. Remove JP 1-5 to disconnect
the internal 250.0-ohm resistor.
The two external precision resistors reduce
the signal by exactly 50%. Set the AIN Block
for a 0-5V range, instead of the default 1-5V
range.
The Externa
l Power Supply “-” and the PCC-
IV
Signal Common “-” must be connected.
The shield connects to the External Power
Supply “-”.
