Allen-Bradley 1769-OF8V Compact IO Analog Output Module

Allen-Bradley 1769-OF8V is an eight-channel voltage-output module for the 1769 Compact I/O family that mounts in a Compact I/O rack to drive analog actuators and provide precise control voltages to instrumentation. Each channel can be configured to one of four voltage ranges—±10 V, 0–10 V, 0–5 V, or 1–5 V—allowing direct interface with a variety of sensors and actuators without external scaling. The module delivers 16-bit resolution plus sign, with an effective 15.89 bits (≈330 μV per LSB) for the ±10 V range, and supports full-scale ranges up to ±10.5 V depending on the selected setting. Conversion rate is up to 5.0 ms for all channels, with a 63% step response under 2.9 ms, enabling moderate-speed control loops. Each output can source up to 10 mA, while typical module supply conditions draw roughly 145 mA at 5.1 V or 125 mA at 24 V, yielding about 2.16 W of dissipation. The eight outputs are single-ended voltage channels, designed for compact I/O backplane operation with compatible Rockwell controllers. Practical applications include generating precise valve or actuator control voltages, interfacing with analog instrumentation, and providing calibrated test signals in automated equipment. As part of the Rockwell Compact I/O ecosystem, the 1769-OF8V is intended for installation in a 1769 rack and used with standard backplane power and communications common to AB’s CompactLogix environments.
