1769-OF4 Visão geral
An analog output module converts controller data into proportional voltage or current signals for actuators, instruments, valves, drives, and process-control equipment. In a current-output configuration, the module drives a standard process-control loop; in voltage-output mode, it supports field devices requiring voltage references. The listed operating ranges are -10 to 10 V, 0 to 10 V, 0 to 5 V, 1 to 5 V, and 0 to 20 mA.
The 1769-OF4 combines four output channels with 16-bit resolution in a CompactLogix module format. Screw connections simplify field wiring and maintenance, while the module is intended for use in modular programmable-controller systems. The verified distributor listing describes the module as a four-channel, single-ended voltage/current analog output module with 24 VDC power and 16-bit resolution.
The module belongs to the broader hierarchy of industrial automation equipment: PLC I/O module, analog output module, CompactLogix I/O, Compact I/O, and programmable-controller peripheral. Its role is to bridge digital controller logic and real-world analog control signals. Because the output signal is generated at the field side, correct grounding, shielding, wiring, and configuration are important in systems where signal integrity affects actuator behavior.
Typical applications include variable-speed drives, proportional valves, pressure and temperature controllers, industrial transmitters, laboratory test equipment, and process-control panels. For a new design, verify controller compatibility, module configuration, output range, grounding, and the required field-device wiring before energizing the system. For an existing installation, preserve the original catalog number and compare configuration data before substituting another module.
This page consolidates verified manufacturer identification, distributor descriptions, technical-document references, application guidance, and replacement cautions for engineers evaluating the 1769-OF4. Because no current unit price was supplied in the verified data, purchasing decisions require a quotation from an authorized distributor or supplier.

Aplicações típicas
1769-OF4 é adequado para 6 aplicaçãos: Proportional Valve Control, Variable-Speed Drive Control, Pressure and Temperature Instrumentation, Industrial Test and Measurement, Flow and Level Control Loops, Factory Automation Commissioning.
Proportional Valve Control
The 1769-OF4 is suitable for driving proportional solenoid valves in a CompactLogix control cabinet when the valve accepts a selected voltage or 0 to 20 mA command. Configure the controller engineering range to match the valve input, then use the module's 16-bit resolution for fine command values. Verify polarity, common grounding, and output range before energizing the field circuit.
Recomendado
Variable-Speed Drive Control
The 1769-OF4 can provide analog reference signals to compatible variable-speed drives when the drive accepts -10 to 10 V, 0 to 10 V, 0 to 5 V, 1 to 5 V, or 0 to 20 mA. The controller must be configured for the drive's command range and signal polarity. Use shielded wiring and proper grounding to reduce electrical noise reaching the drive.
Recomendado
Pressure and Temperature Instrumentation
The 1769-OF4 can represent a controller command for pressure, temperature, or other slow-changing process variables. The selected output range should correspond to the transmitter, indicator, or controller input, while the PLC scaling must match the process engineering units. Because one module provides four channels, it can serve multiple instrument loops when the channel configuration and wiring are planned together.
Recomendado
Industrial Test and Measurement
The 1769-OF4 can generate programmable voltage or current references for automated test panels, calibration equipment, and signal-conditioning checks. Its 16-bit resolution and multiple output ranges provide flexibility when different instruments require different command levels. The application should include calibrated measurement equipment and a documented procedure for verifying each channel's output accuracy.
Recomendado
Flow and Level Control Loops
The 1769-OF4 can drive current- or voltage-input controllers used in flow, level, and chemical-dosing systems. Select 0 to 20 mA when the field instrument uses a current loop, or choose a voltage range that matches the device input. Confirm loop grounding and polarity, and make sure the controller's scaling preserves the required process range and control resolution.
Recomendado
Factory Automation Commissioning
The 1769-OF4 can be used during commissioning to apply controlled analog commands to machinery and verify actuator response before a production process is enabled. The module's four-channel format allows several axes or zones to be commissioned with coordinated controller logic. Use a safe test procedure, limited command ranges, and documented output monitoring to avoid unexpected motion or process conditions.

Principais diferenciais
- Four-channel analog output in one CompactLogix module (vs 1769-OF4CI)
- Multiple voltage ranges plus current output (vs 1769-OF4CI)
- Standard non-isolated module versus isolated related variant (vs 1769-OF4CI)
Notas de projeto
Do not substitute 1769-OF4CI without checking the manufacturer documentation. The verified search results identify the CI model as isolated, but they do not provide enough terminal, electrical, or configuration data to prove pin-to-pin equivalence. Confirm output ranges, channel isolation, power requirements, controller recognition, fault behavior, and terminal assignments before using it as a replacement.
Install the module in the CompactLogix system according to the manufacturer instructions and maintain the required spacing around the module and adjacent equipment. Route field wiring away from high-current conductors where practical, use appropriate shielding for analog signals, and terminate shields according to the system grounding design. Confirm the final installation against the installation instructions identified in the verified documentation.
Verify the 24 VDC supply, protective devices, and grounding before applying power. The 1769-OF4 uses a field-side analog output and its safe operation depends on correct supply and loop wiring. For current outputs, verify that the connected load accepts 0 to 20 mA; for voltage outputs, confirm the selected range and polarity before enabling the channel.
Informações de conformidade
The verified data does not provide RoHS, REACH, lead-free, halogen-free, or conflict-mineral status. The installation-document result mentions IEC 60664-1 and Over Voltage Category II conditions, but no additional compliance claim is inferred.
