Product Overview

The Woodward 5462-948 serves as a high-density, 8-channel Thermocouple (T/C) Input Card designed for the MicroNet and Atlas control platforms. This 100% Brand New and Original module provides the high-fidelity thermal data necessary for critical combustion control and exhaust gas temperature (EGT) monitoring. By utilizing 16-bit analog-to-digital conversion, the card translates low-voltage thermocouple signals into precise digital temperature values. It plays a vital role in turbine protection strategies, enabling the control system to detect thermal gradients and prevent over-temperature conditions in gas and steam turbines, large compressors, and industrial engines.

Engineering Advantages

High-Resolution Thermal Profiling: The 16-bit architecture allows the MicroNet system to resolve minute temperature fluctuations. This precision proves essential for balancing combustion cans in gas turbines, where even slight EGT deviations can indicate fuel nozzle fouling or liner damage.
Integrated Cold Junction Compensation (CJC): The 5462-948 features specialized onboard circuitry that automatically corrects for ambient temperature variations at the terminal connection point. This eliminates the need for external compensation hardware and simplifies field wiring.
Superior Noise Rejection: Woodward employs differential inputs and advanced hardware filtering on each channel. This design effectively suppresses electromagnetic interference (EMI) and radio frequency interference (RFI) common in high-voltage generator environments and turbine decks.
Proactive Sensor Diagnostics: The module continuously monitors each thermocouple loop for open or short-circuit conditions. If a sensor fails, the card immediately alerts the CPU, allowing the control logic to switch to a redundant sensor or trigger a safe shutdown, preventing false trips based on erroneous data.

FAQs

Can I mix different thermocouple types on the same card?

Yes. The Woodward 5462-948 allows you to configure each of the 8 channels independently via the application software. You can monitor Type K and Type J sensors simultaneously on a single card without hardware modification.

Is this card compatible with redundant MicroNet systems?

Absolutely. The hardware supports both simplex and redundant MicroNet/Atlas configurations. In redundant setups, the card ensures seamless data synchronization between the primary and secondary control tiers.

Does the card require periodic field calibration?

While the 5462-948 arrives factory-calibrated, we recommend a yearly loop verification. The integrated CJC reduces the frequency of necessary adjustments compared to legacy analog temperature transmitters.

What mounting precautions should I take?

Ensure the MicroNet chassis power remains OFF during insertion. Align the module carefully with the backplane connectors and tighten the front-panel captive screws to 0.45 N-m (4 lb-in) to ensure proper grounding and vibration resistance.
