Allen-Bradley 1756-OF8 Analog Output Module 8-Channel

Allen-Bradley 1756-OF8 is an eight-channel analog output module designed for Rockwell Automation's ControlLogix platform. It plugs into a 1756 backplane and is commanded by Studio 5xxx software through the ControlLogix I/O architecture, providing eight endpoints for outputting processed control signals. Each channel can be configured independently for voltage or current output, enabling direct interfacing with common actuators such as positioner valves, proportional valve drives, motor speed controllers, or analog indicators without additional signal conditioning. This non-isolated module supports per-channel range configuration and is engineered to deliver consistent, repeatable analog signals in demanding industrial environments, with built-in diagnostics to help monitor channel status and backplane communication. Rockwell also offers isolation and protection variants in the same family, such as 1756-OF8I (isolated) and 1756-OF8K (conformal-coated), providing deployment options for harsher environments or mixed signal architectures.
