About 1794-OE4
The Allen-Bradley 1794-OE4 is an analog output module from the Flex IO product family. This module is used as a component of Distributed I/O node, compatible with Flex I/O communication adapters such as Ethernet, ControlNet, Profibus and Remote I/O. This module features Four (4) user configurable output channels, designed to provide 0 to 20mA, 4 to 20 mA current signals and, +/- 10VDC and 0 to 10 VDC voltage signals signals. Use this module to implement automatic and manual control of modulating devices such as Variable Frequency Drives (VFD), modulating control valves, converters, transducers, dampers, louvers and other Final Control Elements (FCE). The output channels of this module support non-isolated, single ended configuration.
The 1794-OE4 has a resolution of 12 bits plus sign with specific increments and decrements of 2.56mV/cnt for voltage and 5.13µA/cnt for Current. The module’s analog data is stored to a registered formatted as left justified, 16 bit 2’s complement. This register is converted using pulse width modulation method.
