The 1769-OF2 (Part Number: 1769-OF2) is a precision analog expansion module designed for the Allen-Bradley CompactLogix and MicroLogix 1500 controller platforms. This module provides two high-resolution analog output channels, allowing the PLC to control external devices such as variable frequency drives (VFDs), control valves, and actuators. Each channel is individually configurable, offering the flexibility to output either voltage or current signals based on the specific requirements of the field hardware.
Designed for industrial reliability, the 1769-OF2 features integrated bus isolation to protect the sensitive controller backplane from field-side electrical noise and ground loops. Its compact, modular design allows for easy integration into high-density control panels, providing a scalable solution for precise process modulation.

The 1769-OF2 is commonly utilized in closed-loop control systems where proportional regulation is required. Typical applications include:
Modulating steam valves in temperature control loops
Adjusting motor speeds via VFDs in pumping stations
Providing setpoint signals to specialized laboratory equipment
What is the difference between the 1769-OF2 and 1769-OF4?
The 1769-OF2 provides two analog output channels, whereas the 1769-OF4 provides four. The 1769-OF2 is often selected for smaller machines where only a few proportional control points are necessary, reducing hardware costs.
Can I use this module to drive a 4-20mA current loop?
Yes, the module is fully compatible with 4-20mA current loops. You can select the current range via the module configuration software (such as Studio 5000 or RSLogix 500).
