Allen-Bradley 1756-IF6CIS 6-Channel In-Current Sourcing Input Module

The Allen-Bradley 1756-IF6CIS is a six-channel analog input module for ControlLogix that sources current in a current-loop configuration (In-Current Sourcing). Each channel is isolated from the backplane and includes an internal power source, enabling the module to source loop current for 0–21 mA sensors without requiring external per-channel power. Wired through a 20-pin removable terminal block, the 1756-IF6CIS accepts 0–21 mA inputs from field devices such as 4–20 mA transmitters, providing the controller with a direct representation of the current in its channel data. Designed for use in ControlLogix backplanes, it integrates into standard 1756 I/O infrastructure and is suitable for process control and automation applications that monitor current-loop sensors such as pressure, flow, and temperature transmitters. Typical configurations expose channel status and fault information to the controller for diagnostics, consistent with other 1756 analog I/O modules.
