Drive Different Loads
with the 1756-OF8I Module
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, publicat
.

IMPORTANT: Remember the following:
• If separate power sources are used, do
not exceed the specific isolation
voltage. For more information on
