The Allen-Bradley 1756-OF8H is an analog output module designed for Rockwell Automation’s ControlLogix Logix controller platform.
It features eight voltage or current output channels and includes a built-in Highway Addressable Remote Transducer (HART) modem that enables communication with HART-compatible field devices.
Each channel is independently configurable for 0–20 mA or 4–20 mA current outputs, as well as ±10 VDC voltage outputs.
The module provides a resolution of approximately 15–16 bits across all ranges, ensuring high-accuracy analog signal generation.
The 1756-OF8H is ideal for process control and industrial automation applications that require HART-based field device integration and precise analog output performance.
