Allen-Bradley 1756-OF6CI ControlLogix 6-Ch Output Module

Allen-Bradley 1756-OF6CI is a ControlLogix isolated analog output module that provides six current-output channels for control of analog field devices. Each channel is electrically isolated from the others and from the backplane, helping prevent ground-loop issues and cross-channel interference in demanding industrial environments. The module is designed for ControlLogix I/O backplanes and supports floating-point data in Studio 5000/Logix Designer configurations, enabling precise setpoints to drive analog actuators, valves, and other control elements via current-loop outputs. Fault and status reporting on the 1756-OF6CI helps identify channel faults or out‑of‑range conditions, improving diagnostic capability and system reliability. Per-channel burden is specified as 0–550 Ω or 551–1000 Ω depending on configuration, supporting a range of common field devices and loop installations. This six-channel isolated current-output module integrates into a ControlLogix chassis to convert digital control signals into stable, isolated analog current signals for multiple process loops, making it a versatile choice for scalable analog control within Rockwell Automation ecosystems.
