FUNCTIONAL DESCRIPTION:
The 5464-338 is a high-precision 12-Channel RTD (Resistance Temperature Detector) Input Module designed and manufactured for the Woodward MicroNet control systems. It serves as a specialized interface for monitoring critical temperatures in industrial prime movers, including turbine bearing temperatures, generator winding temperatures, and lubricating oil temperatures. By converting resistive changes into high-resolution digital data, it provides the thermal feedback necessary for protective monitoring and governing.
PRECISION THERMAL SENSING
Each of the 12 channels is designed for 3-wire RTD configurations. This setup is essential for industrial applications where sensors are located far from the control cabinet, as the third wire allows the module to measure and cancel out the lead-wire resistance, ensuring a true temperature reading at the sensor tip. The 16-bit resolution allows the MicroNet system to detect minute thermal trends before they reach critical alarm levels.
GALVANIC ISOLATION AND NOISE IMMUNITY
Thermal sensors in power plants are often subject to significant electromagnetic interference (EMI). The RTD Input Module incorporates 500 Vdc of galvanic isolation between the field inputs and the internal backplane logic. This robust protection prevents ground loops and ensures that high-voltage transients in the field do not damage the central CPU or other I/O modules within the MicroNet chassis.
SOFTWARE-SELECTABLE CONFIGURATION
The module is highly versatile, supporting multiple Platinum RTD standards. The specific RTD type (100-ohm or 200-ohm) and the corresponding temperature ranges are software-selectable through the MicroNet engineering environment. This eliminates the need for manual hardware jumpers or physical calibration, allowing for rapid system deployment and easier maintenance during sensor upgrades.

What is the Woodward 5464-338?
The 5464-338 is a 12-channel RTD Input Module for the MicroNet control system. It measures the resistance of Platinum RTDs to provide accurate temperature feedback for turbine and engine control.
How does the RTD Input Module handle lead-wire resistance?
The module utilizes a 3-wire measurement technique. By measuring the resistance of the lead wires independently, the module's internal circuitry subtracts that value from the total resistance, providing a highly accurate temperature measurement regardless of the distance to the sensor.
What happens if a temperature sensor fails?
The RTD Input Module features continuous loop diagnostics. If a sensor wire breaks (open circuit) or shorts out, the module immediately detects the out-of-range resistance and flags a fault to the MicroNet CPU, which can then trigger an alarm or switch the control logic to a redundant sensor.
Can the 5464-338 be used with Copper RTDs?
The RTD Input Module is primarily optimized for Platinum RTDs (100-ohm and 200-ohm). For applications requiring Copper RTD inputs, you should verify the software configuration options or consult with our technical team to ensure compatibility with your specific sensor type.
