Features:

  • Serves as the isolated voltage output interface between the CompactLogix controller and field instrumentation
  • Integrates four independent 0-10V DC channels with 15-bit resolution and individual galvanic isolation
  • Functions within standard CompactLogix 1769 chassis configurations requiring no field calibration
The Allen-Bradley 1769-OF4VI operates as the isolated analog voltage output module in a CompactLogix system, providing four independent 0 to 10V DC channels to field devices within the rack. It continuously generates precise analog control signals across a full-scale range of 0 to 10.5V with 15-bit resolution at 330 μV per bit and delivers these outputs through individually isolated channels to support steady-state operation of proportional valves, variable frequency drives, and positioning actuators.

The 1769-OF4VI provides essential analog output functions for the CompactLogix control system, and is a critical component of the process control path, directly affecting the proper, normal operation of voltage-controlled field instrumentation. One or more 1769-OF4VI modules may be installed per chassis depending on the required output channel count.

For applications requiring robust output protection, the 1769-OF4VI incorporates internal short-circuit safeguarding across all four isolated channels. In addition to standard voltage output operation, the protective configuration also performs automatic current limiting. The 1769-OF4VI protection system executes fault response using the internal circuitry specified in the module design. Using this method, the isolated output system continually monitors the current level of each channel. If the module detects that an output channel has exceeded the maximum short-circuit threshold of 42mA, it will automatically limit the current to protect the internal circuitry and preserve the operational integrity of the remaining three channels.

The 1769-OF4VI Allen-Bradley Isolated Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Allen-Bradley 1769-OF4VI is a compact isolated analog output module engineered for the CompactLogix control platform. As a four-channel isolated voltage output module, the 1769-OF4VI is specifically designed to deliver precise, independent 0 to 10V DC analog control signals across multiple output channels while maintaining complete electrical isolation between each channel. This product addresses the critical industrial challenge of ground loop interference and signal crosstalk that commonly plagues non-isolated analog output modules, solving the problem of channel-to-channel electrical noise contamination in multi-device control schemes. By providing four individually isolated outputs, the 1769-OF4VI ensures superior signal integrity and system reliability in environments where potential differences between field devices and control systems could otherwise compromise analog output accuracy and overall process stability.

The 1769-OF4VI isolated analog output module is ideally suited for applications requiring precise voltage control with galvanic isolation between control channels. Typical application domains include process control systems, variable frequency drive (VFD) speed reference control, proportional valve positioning, damper and actuator control, and automated machinery requiring synchronized multi-channel analog references. The 1769-OF4VI is particularly valuable in industries such as oil and gas, chemical processing, water and wastewater treatment, pharmaceutical manufacturing, and food and beverage automation, where isolated 0-10V signals are essential to prevent ground loop issues and ensure accurate analog control across distributed field instrumentation. The 30V DC operating voltage with IEC Class 2 reinforced insulation makes the 1769-OF4VI suitable for installations requiring enhanced safety margins and strict regulatory compliance.

The Allen-Bradley 1769-OF4VI supports an 8-module power supply distance rating and accepts solid wire connections ranging from 22 to 14 AWG, facilitating straightforward field wiring practices and reliable terminal connections. The 1769-OF4VI includes a replacement door kit to maintain proper terminal protection and labeling integrity over the module's service life. When integrating the 1769-OF4VI into a CompactLogix system, engineers should verify that the 5V DC backplane power budget adequately accommodates the 165mA bus current requirement and that proper heat dissipation is planned for the 2.0-watt thermal load, particularly in high-density I/O configurations where multiple modules are installed in close proximity.
