Allen-Bradley 1756-OF8IH ControlLogix 8-Point HART Analog Output Module

Allen-Bradley 1756-OF8IH is a ControlLogix eight-point isolated analog output module with integrated HART support. It provides eight independent A/O channels that are isolated from the backplane and from each other, enabling safe, multi-channel signaling for field devices in the same chassis. The onboard HART capability lets you communicate with HART-compatible transmitters and actuators for configuration, device status, and basic diagnostics without requiring external hardware. Designed for use with 1756 ControlLogix I/O backplanes, it is configured and monitored through Rockwell’s Studio 5000 Logix Designer, aligning with contemporary ControlLogix system architectures. Typical applications include process control loops and instrumentation tasks where multiple actuators or transducers must be driven with isolated outputs while leveraging HART data to optimize performance and maintenance. This module’s eight channels support per-channel output configuration within the ControlLogix framework, and the isolation enhances signal integrity and safety in multi-channel installations.
