1769-OF8V | Allen-Bradley Analog Output Module Supplier

Product Overview: 1769-OF8V Analog Output Module

When your automation system demands reliable voltage output control, the 1769-OF8V from Allen-Bradley provides a compact, high-resolution solution. As part of the Compact I/O family, this analog output module integrates seamlessly with CompactLogix and MicroLogix 1500 controllers. It offers eight single-ended channels configurable for ±10V dc, 0 to 10V dc, 0 to 5V dc, or 1 to 5V dc ranges, making it suitable for a wide variety of industrial applications.

Key Features & Technical Specs of the 1769-OF8V

• Eight single-ended outputs provide independent voltage control for multiple actuators or signal receivers.
• Analog ranges include ±10V dc, 0 to 10V dc, 0 to 5V dc, and 1 to 5V dc, with full-scale ranges extending to ±10.5V dc and -0.5 to 10.5V dc.
• Digital resolution of 16 bits plus sign delivers fine granularity: 15.89 bits for ±10V dc, 14.89 bits for 0 to 10V dc, 13.89 bits for 0 to 5V dc, and 13.57 bits for 1 to 5V dc, all at 330 µV/bit.
• Conversion rate of 5 ms ensures timely updates for dynamic control loops.
• Bus current draw is 145 mA at 5V dc and 135 mA at 24V dc, keeping power demands low.
• Overall accuracy of ±0.5% full scale at 25 °C (77 °F) guarantees reliable signal output.
• No field calibration required—accuracy is assured by hardware design.
• Power supply distance rating of 8 allows flexible placement within the I/O bank.
• Slot width of 1 minimizes rack space usage.

Applications & Use Cases for the 1769-OF8V

In process control environments, the 1769-OF8V excels at driving analog actuators, valves, and variable frequency drives. For example, a packaging line can use its 0 to 10V dc outputs to precisely adjust conveyor speed or tension. Similarly, in a water treatment plant, the module’s ±10V dc range can control chemical dosing pumps with high accuracy. Its compact form factor makes it ideal for distributed control panels where space is at a premium.

Installation Guide for the 1769-OF8V

Mount the 1769-OF8V in any slot of a CompactLogix or MicroLogix 1500 chassis using the standard DIN rail or panel mounting method. Ensure proper grounding of the module and signal wiring to minimize noise pickup, as single-ended wiring is more susceptible to electrical disturbance. Use copper wire rated for 90 °C (as specified in the data) with solid wire sizes from 22 to 14 AWG or stranded wire from 22 to 16 AWG. The module supports a power supply distance rating of 8, meaning it can be placed up to eight modules away from the power supply without additional considerations.

Maintenance & Reliability Tips

The 1769-OF8V requires no field calibration, reducing maintenance overhead. Periodically inspect the module for signs of damage or contamination, and verify that all wiring connections remain secure. The module’s open enclosure design means it should be installed in a clean, dry environment within an IP-rated cabinet. With proper care, the module delivers consistent performance over its service life.

Compatibility & Integration

The 1769-OF8V is compatible with MicroLogix 1500 and CompactLogix controllers. It supports multiple data formats including Raw/Proportional data, Engineering units, Scaled for PID, and Percent full range, simplifying integration with various control strategies. The module communicates over the backplane of the Compact I/O system, requiring no additional communication cables beyond the standard 8-point cable.
