Simplified Circuit Schematics Appendix D
Output Channel Circuits The ControlLogix high-speed analog I/O module uses two output channels
(0…1). The figure below shows the simplified schematic for each output channel.
IMPORTANT The figure shows the circuit for output channel 0. Output channel 1 is exactly
the same with the exception that the terminals on the left side of the circuit are
labelled for each specific channel. For example, channel 1 uses V out-1 and
I out-1.
