Allen-Bradley 1769-OF8V CompactLogix 8-Channel Analog Voltage Output Module
Configured for precision analog voltage command generation in CompactLogix and MicroLogix 1500 systems, the Allen-Bradley 1769-OF8V (1769-OF8V Analog Output Module) provides direct physical/electrical execution. The module drives up to eight single-ended analog voltage channels across selectable ranges (0 to 10 VDC, 0 to 5 VDC, 1 to 5 VDC, and +/- 10 VDC) with 16-bit signed resolution, executing overall full-scale conversion loops in 5 ms.

Industrial Control & Drive Integration
The analog output module relies on backplane bus communication velocity to process incoming register data directly from the system controller. Configuration profiles enforce firmware flash compatibility across connected scan cycles, ensuring deterministic parameter execution without data truncation. Support for EtherNet/IP deterministic networks enables real-time distribution of output commands across networked field devices.
Frequently Asked Questions
Q: Can the 1769-OF8V module be removed or inserted into the CompactLogix rack while system power is active?
A: No, the 1769-OF8V module does not support Removal and Insertion Under Power (RIUP). Removing or inserting the unit while backplane power is applied causes controller faults and risks permanent damage to the module interface circuits.
Q: Does the 1769-OF8V analog output module require routine field calibration?
A: No, hardware design guarantees calibration stability across factory-set operational parameters. Internal circuit references eliminate the need for manual potentiometers or periodic field calibration adjustments.
Field Installation Guidelines
Mount the 1769-OF8V module directly on a standard 35 mm DIN rail or secure it to a panel using mounting screws. Verify that the module is positioned within 8 slots of the system power supply to comply with the power supply distance rating. Route output wiring using twisted-pair shielded copper cable rated for at least 90 deg C, keeping signal lines separate from AC power conduits and variable frequency drive outputs. Connect signal wire shields to a single chassis earth ground point at the enclosure side to prevent ground loops from degrading analog signal accuracy.
