Allen Bradley 1756-OF4 ControlLogix Analog Output Module

The Allen Bradley 1756-OF4 is a high-precision analog output module designed for seamless operation within ControlLogix programmable automation systems. Engineered by Rockwell Automation, this module provides accurate and reliable analog signals for controlling various industrial devices such as actuators, valves, and process instrumentation.

The 1756-OF4 offers four individually configurable analog outputs, supporting both voltage (±10V) and current (4…20 mA) output ranges. This flexibility allows it to meet the needs of diverse industrial automation tasks—from process control to motion systems—requiring precise analog control.

With 15-bit resolution, the module ensures fine signal granularity and stability, enabling accurate command of output devices. Each channel’s output quality is maintained with minimal signal noise, supporting critical operations where precision is key. The module also features advanced calibration and diagnostics, simplifying maintenance and enhancing system reliability.

The 1756-OF4 is compatible with standard ControlLogix chassis and uses 1756-TBNH or 1756-TBSH removable terminal blocks for quick installation and wiring. It draws 150 mA at 5V and 120 mA at 24V from the backplane and can dissipate up to 4.9 Watts at 60°C.

With 50V continuous isolation voltage, it provides safe and consistent performance in industrial environments. Though it comes without an enclosure, it is designed for installation inside control cabinets as part of a larger system.

Whether used in manufacturing, energy, or process automation, the Allen Bradley 1756-OF4 delivers dependable analog output performance, helping improve control accuracy and system responsiveness in demanding industrial applications.
