Allen-Bradley 1756-IF8 ControlLogix 8 Point Analog Input Module
Control Logix 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, Control Logix analog I/O modules produce information when needed while providing additional system functions.
