Functional Description
5466-253 is a Analog Combo Module developed by Woodward. It is equipped with circuitry to handle a diverse range of inputs and outputs, making it suitable for a wide array of applications. This module boasts four speed sensor inputs, eight analog inputs, four analog outputs, and two proportional actuator driver outputs, enhancing its flexibility and adaptability. The speed sensor inputs cater to different types of speed sensors, accommodating both magnetic pick-up and proximity probe inputs. This capability ensures seamless integration with various types of rotating machinery and equipment, providing precise and accurate speed measurement.
Features
- For analog inputs, the High Density Analog Combo module supports 4-20 mA input signals. This range is widely used in industrial control and measurement applications, allowing seamless connectivity with a variety of sensors, transducers, and other analog devices.
- In terms of actuator driver outputs, the module offers two proportional actuator driver outputs, each configurable for either 4-20 mA or 20-160 mA operation. This versatile configuration enables seamless compatibility with different types of proportional actuators, empowering precise control over valves, motors, and other proportional devices.
- The module's integration of multiple functionalities into one unit not only saves space but also simplifies system design and reduces wiring complexity. This consolidation of inputs and outputs streamlines the installation process and enhances system reliability, as there are fewer points of potential failure.
- The module's robust design and high-quality components ensure reliable and consistent performance, even in demanding industrial environments. Its adaptability and compatibility with various sensor types and actuator devices make it an ideal choice for industries such as power generation, oil and gas, petrochemicals, and more.
Analog Inputs
- The analog inputs in the system must be of the current type as specified in Appendix A, which provides specific part numbers for reference. Notably, all modules across the system utilize the same cable and Fault Tolerant Modules (FTMs), ensuring uniformity and compatibility.
- Regarding the current inputs, there are two options for transducer usage: two-wire ungrounded (loop powered) transducers or isolated (self-powered) transducers. Both types can be seamlessly integrated into the system.
- To ensure reliable and accurate readings, all analog inputs boast an impressive 200 Vdc of common mode rejection, minimizing the impact of common-mode noise and disturbances on the measurements.
- However, when interfacing with a non-isolated device that has the potential to reach over 200 Vdc with respect to the control's common, an additional precautionary step is recommended. The use of a loop isolator is advised to break any return current paths that may lead to erroneous readings. This precautionary measure ensures the integrity of the data and prevents potential issues arising from ground differences.
- In the design of all current inputs, 200 ohm resistors are placed across their inputs. This further enhances accuracy and stability, contributing to the overall precision and reliability of the analog input measurements.
- The implementation of these features ensures that the system can effectively handle a wide range of analog input scenarios while maintaining accuracy and safety. By adhering to the recommended practices and precautions, the system can reliably process current inputs from various transducer types, making it suitable for a diverse range of industrial applications.

Frequently Asked Questions
What is 5466-253?
It is an Analog Combo Module developed by Woodward.
How are faults monitored in the analog outputs?
Each analog output is equipped with fault detection capabilities. The output actively monitors the output source current for potential faults, allowing the system to detect any abnormalities or issues promptly.
Can individual analog outputs be disabled when needed?
Yes, all of the analog outputs can be individually disabled, providing flexibility in system control and operation. This feature allows specific outputs to be selectively turned off, if required, without affecting other channels.
What happens when a channel or module fault is detected in the analog outputs?
When a fault is detected in either a specific channel or the entire module, the application program can take appropriate actions. It may annunciate the fault, raising alarms or notifications to alert operators. Additionally, the application program can disable the affected channel or module to prevent further issues.
