1794-OE12 | Allen-Bradley | FLEX I/O High-Density Analog Output Module

Product Overview

The Allen-Bradley 1794-OE12 functions as a high-density analog output interface within the FLEX I/O family. It provides 12 single-ended channels, allowing a single module to drive a vast array of actuators, valves, and motor controllers from a decentralized location. This module streamlines complex control architectures by providing precise voltage and current signals without the bulk of traditional rack-based I/O. We provide this unit as 100% Brand New and Original, ensuring your automation system operates with factory-certified precision and zero previous field wear.

Technical Specifications

Engineering Advantages

• High-Density Channel Integration: The 1794-OE12 manages 12 analog outputs within a single slim module. This density drastically reduces the number of required adapters and terminal bases, cutting down on both hardware costs and control cabinet footprint.

• Precision 16-Bit Signal Control: The integrated Digital-to-Analog Converters (DAC) deliver 16-bit resolution. This provides the ultra-fine granularity required for sensitive positioning tasks or precise chemical flow regulation where low-resolution modules fail to meet tolerances.

• Flexible Signal Mapping: You can configure each channel independently for current (mA) or voltage (V) operation. This versatility allows you to standardize your spare parts inventory, as one 1794-OE12 can replace multiple specialized low-density cards.

• Robust Load Drive Capability: The module drives resistive loads up to 750 Ω in current mode. This ensures consistent signal strength even over long cable runs to field devices located far from the I/O enclosure.

• Distributed I/O Efficiency: As part of the FLEX I/O series, the 1794-OE12 mounts directly on the machine or near the process. This decentralized approach reduces the massive copper wiring bundles associated with centralized PLC racks, effectively lowering installation labor and material costs.

FAQs

• Does this module ship in original Allen-Bradley factory packaging?

  Yes. We guarantee that every 1794-OE12 unit we sell is 100% Brand New. It arrives in its original factory-sealed box with all original documentation and labels intact.

• Which terminal base is required for the 1794-OE12?

  This module requires the 1794-TB3G or 1794-TB3GS terminal base. These bases provide the grounded chassis screw necessary for landing cable shields, which is essential for protecting 16-bit analog signals from electromagnetic interference.

• How do the status indicators assist in system maintenance?

  The module features a bi-color (Green/Red) status LED. A steady green light confirms the module is powered and functional, while a red light immediately alerts technicians to internal hardware faults or configuration mismatches, speeding up the troubleshooting process.

• Can I use this module with any FLEX I/O adapter?

  The 1794-OE12 is compatible with most FLEX I/O communication adapters, including EtherNet/IP (1794-AENTR), ControlNet (1794-ACN15), and PROFIBUS (1794-APB) adapters.
