Allen-Bradley 1794-OE12 Flex I/O Analog Output Module

Description

The Allen-Bradley 1794-OE12 Flex I/O Analog Output Module is a high-density module belonging to the Flex I/O product line, designed for industrial analog signal output applications. It features 12 single-ended output channels, each configurable to output 0-20mA, 4-20mA current signals, or +/-10V DC voltage signals to meet diverse industrial control needs. Equipped with 16-bit resolution, the module uses a two’s complement data format and an internal analog-to-digital converter (ADC) to convert digital data to precise analog signals, delivering an absolute accuracy of 0.1% full scale at 25 degrees Celsius, with a precision drift of 0.004% full scale per degree Celsius for both voltage and current configurations.

Key technical specifications include a 10.5-31.2V DC power supply, 80mA Flexbus current, and maximum power consumption of 7.68W at 24V DC. It provides continuous 50V isolation between field and system, withstanding 850V AC testing for 60 seconds. The module has a compact footprint of approximately 46x94x54mm, with terminal block screw torque rated at 0.8N·m, and features red-green power/status indicators for quick operational status checks. Designed with a non-isolated channel layout and open housing (requiring installation in a protective enclosure), it supports single-ended cabling and is compatible with terminal bases such as 1794-TB3G and 1794-TB3GS with key switch position 4. Ideal for use in steel mills, power plants, cement plants, automotive manufacturing, and other heavy industrial applications.
