2. Product Overview:

The WOODWARD 5501-1428 is an 8-channel Analog Output (AO) Module designed for use within Woodward’s MicroNet Digital Control Series (including MicroNet Plus and MicroNet TMR systems). This module takes digital commands from the central processing unit (CPU) and converts them into precise analog current (e.g., 4-20 mA) or voltage (e.g., 0-5 Vdc, 0-10 Vdc) signals. These signals are then used to drive actuators, valves, variable speed drives, or other field devices, enabling accurate and dynamic control of machinery and industrial processes.

• Product Type: Analog Output (AO) Module

3. Detailed Product Description:

For any automated industrial process, the ability to precisely manipulate physical parameters is as crucial as the ability to measure them. The WOODWARD 5501-1428 serves this vital function by providing the MicroNet control system with the capability to send accurate analog commands to the field.

The 5501-1428 is an 8-channel Analog Output Module that integrates seamlessly into a MicroNet chassis. Each of its eight independent channels can be configured to generate standard analog output signals. These typically include:

• Current Outputs: Such as the robust and commonly used 4-20 mA current loop, ideal for driving proportional valves, actuators, and other control elements over long distances.
• Voltage Outputs: Such as 0-5 Vdc or 0-10 Vdc, used for various control applications where voltage signaling is preferred.

The module receives digital values from the MicroNet CPU, converts these digital values into corresponding high-resolution analog signals, and then drives the connected field devices. This precise control allows the system to:

• Regulate Control Devices: Accurately position valves (e.g., fuel valves, steam valves, compressor bypass valves) to control flow, pressure, or temperature.
• Adjust Drives and Motors: Control the speed of variable frequency drives or the output of motors.
• Provide Setpoints: Send analog setpoints to other local controllers or instrumentation.

The 5501-1428 is designed for high reliability and accuracy in demanding industrial environments. It typically features electrical isolation between channels and from ground, which is essential for preventing ground loops and protecting the control system from electrical noise or faults in the field wiring.

Like many modern Woodward modules, it’s often a “no-potentiometer, no-calibration” design. This simplifies installation and replacement, as no manual adjustments are needed, reducing maintenance time and potential human error. It often supports automatic module detection, meaning the CPU can identify the module’s presence and type, further streamlining setup.

Key Features and Benefits:

• 8 Independent Analog Output Channels: Provides high-density output capability for controlling multiple devices.
• Versatile Signal Generation: Supports common industrial analog output signals like 4-20 mA and various voltage ranges.
