High-Precision Analog Outputs for Industrial Automation
The Allen-Bradley 1769-OF4CI provides four differential, individually isolated analog outputs for precise industrial control. Each channel supports 0–20 mA or 4–20 mA signals, driving actuators and devices reliably. Moreover, it integrates directly with MicroLogix 1500 and CompactLogix controllers for flexible automation applications.
Key Features and Advantages
- Four independently isolated analog output channels for reliable multi-device control
- Supports 0–20 mA and 4–20 mA current ranges for versatile industrial signals
- Compact single-slot design saves panel space without sacrificing performance
- Compatible with all 1769 CompactLogix controllers, including series A and B
- High-resolution 16-bit output ensures precise current regulation and signal stability
