1769-OF8V | Allen-Bradley CompactLogix 8-Channel Analog Voltage Output Module

The 1769-OF8V is a high-density analog voltage output module manufactured by Allen-Bradley, part of the Compact I/O product family. It features eight (8) single-ended analog output channels that can be configured for voltage ranges such as ±10V DC, 0–10V DC, 0–5V DC, and 1–5V DC. This module is typically used in process control and industrial automation systems, where it translates digital output signals from a controller into precise voltage signals for actuators, signal converters, or analog indicators. It is compatible with MicroLogix 1500 and CompactLogix controllers, offering compact size and reliable performance for a wide range of mid-sized applications.

No, the 1769-OF8V module is factory-calibrated, and no field calibration is necessary. Calibration is guaranteed by the hardware design, making installation and long-term operation simple and maintenance-free. The device is engineered to maintain high precision with an overall accuracy of ±0.5% full scale at 25 °C (77 °F). It also features short-circuit protection and voltage overshoot safeguards to protect both the module and connected devices.

This module draws 145 mA at 5V DC and 135 mA at 24V DC from the CompactLogix or MicroLogix backplane. The power supply distance rating is 8, meaning it can be located up to 8 modules away from the power supply in a CompactLogix rack. For Series A modules, only backplane power is supported, while Series B modules support external 24VDC power for added flexibility. Powerup time is under 5 milliseconds, making the module responsive during system initialization.

The module supports multiple analog data representations, including:

• Raw/Proportional data (for use in basic control loops),
  
• Engineering units (scaled to real-world values),
  
• Scaled-for-PID format (suitable for advanced control applications), and
  
• Percent full range (helpful in visualizations and dashboards).

These formats allow integrators and engineers to choose the appropriate signal representation depending on their application and controller configuration strategy.

The 1769-OF8V occupies one slot in the CompactLogix or MicroLogix chassis. It is designed for use in open-type enclosures and conforms to typical panel-mount environments. The module dimensions are approximately 4.65 x 1.38 x 3.43 inches, and it weighs around 0.58 lbs. It should be installed on a DIN rail with appropriate spacing for heat dissipation and system serviceability.
