Overview
The Allen-Bradley 1756-OF8 is a ControlLogix 8 point analog output module designed for flexible voltage and current signal generation in industrial automation systems. This module within the ControlLogix series features 8 outputs with flexibility for either voltage or current use, operating with an output voltage range of -10 to 10 volts and supporting an output current range of up to 20 milliamperes. The unit is part of ControlLogix series and uses an R-Ladder DAC module conversion method.
