Product Overview

The 1756-OF8IH is an Allen-Bradley ControlLogix isolated analog output module featuring eight individually controllable 4-20 mA output channels with HART communication capability. It integrates within a ControlLogix rack to provide isolated analog outputs plus HART pass-through and device configuration. Commonly used for field instrumentation control and data diagnostics in process and discrete industrial environments, it enables both analog control and HART variable communication in a single module.
