Isolated Analog Input Module 4
Publication 1771Ć5.62 - November 1998
The module has configuration jumpers for determining the input type
(voltage or current) for each input. The module is shipped with the
configuration jumpers positioned for voltage mode. You can
select either voltage or current for each input.
Key the Backplane
Connector
Place your module in any slot in the chassis
except the leftmost slot which is reserved for
