Drive Different Loads With The 1756-Of8I Module - Allen-Bradley 1756-IF8I User Manual

Chapter 5 1756-OF8I Isolated Analog Output Module
IMPORTANT: Remember the following:
• If separate power sources are used, do
not exceed the specific isolation
voltage. For more information on
module specifications, see the 1756
ControlLogix I/O Specifications
Technical Data, publication
1756-TD002.
• Place additional devices anywhere in
the loop.

When the 1756-OF8I module operates with a Current output load, each channel
automatically adjusts its output power for 0...1000 ohm loads. The module's 24V
backplane current requirements vary based on load.
For more information the module's 24V current requirements, see the 1756
ControlLogix® I/O Specifications Technical Data, publication 1756-TD002.
