Product Overview
The 1769-OF4CI is a high-precision analog output module engineered for Allen-Bradley CompactLogix and MicroLogix 1500 systems. It features four individually isolated current output channels, specifically designed to drive field devices such as valve positioners, actuators, and speed controllers. The "I" in the model number signifies individual channel-to-channel isolation, a mechanical necessity for systems where ground loops or electrical interference between loops could compromise signal integrity. With 16-bit resolution and support for standard 4–20 mA and 0–20 mA ranges, the 1769-OF4CI provides an authoritative solution for critical process control loops that demand high accuracy and electrical robustness.
