The Allen-Bradley 1756-OF6CI ControlLogix Analog Output Module is a six-channel isolated current-output card for ControlLogix I/O backplanes. Each channel provides an isolated 0–21 mA output with 13-bit resolution across the full range, enabling precise control of actuators, valves, and other process devices. The module uses a 20-pin terminal interface and supports loads wired as OUT and RTN for 0–550 Ω, or as OUT and ALT for 551–1000 Ω configurations. Backed by the 1756 ControlLogix backplane, the 1756-OF6CI draws up to 250 mA from a 5.1 V supply to drive the specified loads.
