Allen-Bradley 1756-OF8 ControlLogix 8 Point Analog Output Module
Allen-Bradley 1756-OF8
ControlLogix analog I/O modules are interface modules that convert analog signals to digital values for inputs and convert digital values to analog signals for outputs. Controllers can then use these signals for control purposes.
Using the producer/consumer network model, ControlLogix analog I/O modules produce information when needed while providing additional system functions.
