1769-OF4CI | Allen Bradley | CompactLogix Isolated Analog Current Output Module

Product Overview

The Allen Bradley 1769-OF4CI provides high-density analog output capabilities for CompactLogix and MicroLogix 1500 control systems. This 100% brand new original module features four differential, individually isolated current channels. Isolation between channels prevents ground loops and ensures signal integrity in complex electrical environments, making it a critical component for driving actuators, variable frequency drives (VFDs), and other current-loop field devices.

Engineering Advantages

• Individual Channel Isolation: This module eliminates crosstalk and ground loop interference by providing complete electrical isolation for each of the four channels. This architecture protects the controller from field-side surges and noise.

• Maintenance-Free Precision: The hardware design guarantees accuracy without the need for periodic field calibration. This reduces long-term maintenance costs and minimizes system downtime.

• Flexible Data Scaling: The module supports multiple data formats, including scaling for PID loops and engineering units. This allows engineers to map output values directly to process variables without complex PLC code.

• Compact High-Density Control: Occupying only a single slot width, the 1769-OF4CI delivers four isolated paths in a small footprint. This optimizes cabinet space while maintaining high-resolution 16-bit performance for precision applications.

FAQs

• Is this 1769-OF4CI module original and new?

  Yes, we supply only 100% brand new and original Allen Bradley hardware in its original factory packaging.

• Can I use this module with a MicroLogix 1500 controller?

  Yes, the 1769-OF4CI remains fully compatible with both the MicroLogix 1500 and the CompactLogix controller families.

• Does this module require external calibration software?

  No, the module utilizes a hardware-based calibration design that ensures accuracy for the life of the product without manual intervention.

• What is the maximum distance this module can be from the power supply?

  The module carries a power supply distance rating of 8, meaning it must stay within 8 slots of a 1769-PA2, PB2, PA4, or PB4 power supply.
