Selecting the
Number of
Channels
If you examine the rear of the module, you will notice four banks of jumpers. The
module has several options that you can select by installing or removing these
jumpers:
S
A bank of eight jumpers to set voltage or current input for each
channel.
S
A bank of four jumpers to select the signal range for all active channels.
S
A bank of three jumpers to select the number of channels used.
S
A bank of two jumpers to select unipolar or bipolar signal range for all
active channels.
The module is set at the factory for a 4–20 mA signal range on all eight channels
with unipolar polarity. The following diagram shows how the jumpers are set at the
factory and describes the function of each jumper. When removing a jumper, store it
by placing it on a single pin to prevent losing it.
