operational power from the backplane. +24V dc power must be
applied to your module before operation. If power is not
applied, the module position will appear to the adapter as an
empty slot in your chassis. If the adapter does not recognize
your module after installation is completed, cycle power to the
adapter.

Inputs/Outputs

Each 1794-IE8H input can be operated from an analog field device signal, and
each 1794-OE8H output channel can operate an analog field device.
The channels of the 1794-IE8H are electrically connected to each other and
have a common plus-line. The channels of the 1794-OE8H are electrically
connected to each other.
When interconnecting several lines, you must consider the total
