High Accuracy Allen Bradley 1756-OF6CI Analog Output Module For ControlLogix Systems

Product Overview

The Allen-Bradley 1756-OF6CI is a high-resolution, 6-channel analog current output module engineered for Rockwell Automation ControlLogix systems. It converts 16-bit digital data into precise 4–20 mA signals for direct control of actuators, valves, drives, and other field devices. Built for harsh industrial environments, the module offers channel-to-channel isolation, onboard diagnostics, and automatic calibration to ensure maximum uptime and process accuracy.

Key Features

• ControlLogix Compatible – Slots directly into any 1756 chassis with a 1756 backplane
• 6 Isolated Current Outputs – 4–20 mA range per channel, 16-bit resolution (0.34 µA/bit)
• High Accuracy – ±0.15 % full scale at 25 °C, ±0.3 % full scale over full temperature range
• Field Calibration – Automatic calibration eliminates drift without removing wiring
• Advanced Diagnostics – Open-wire, short-circuit, and over-range detection with per-channel status LEDs
• Configurable Data Formats – Engineering units, proportional counts, or IEEE-754 floating point
• Removable Terminal Block (RTB) – 1756-TBNH or 1756-TBSH for fast wiring and maintenance
• Conformal Coating Option – 1756-OF6CIXT for corrosive or high-humidity environments
