1794-OE12
The Allen-Bradley 1794-OE12 is a high-density analog output module that is part of the Flex IO product family. This
module features Twelve (12) output channels configurable for 0-20mA, 4-20 mA current signals and +/-
10VDC voltage signals. The module’s channels are non-isolated and supports single-ended wiring configuration.
The 1794-OE12 is used with terminal bases such as 1794-TB3G and 1794-TB3GS with keyswitch position
4. It has an open-type enclosure which means this module and the entire Flex I/O assembly must
be installed inside an enclosure that offers adequate protection against industrial elements.
The 1794-OE12 comes with an internally installed analog to digital circuit (ADC) converter. It converts digital
data to analog signal with conversion resolution of 16 bit in 2’s complement data format. Each output
channels has an absolute accuracy of 0.1% Full Scale @ 25 °C, both for Voltage and Current signals with accuracy drift of 0.004% full scale/°C on both signal configuration.
