Woodward 5462-948 MicroNet Thermocouple Board 5462-948

Product Overview

The 5462-948 (Part Number: 5462-948) is a high-density, industrial-grade thermocouple input card engineered by Woodward for the MicroNet and Atlas control platforms. Designed to facilitate precision thermal monitoring in complex power generation and propulsion systems, this module provides eight independent channels for simultaneous temperature acquisition.

The 5462-948 (Model: 5462-948) acts as a critical interface between field-mounted thermocouple sensors and the controller's digital logic. By implementing high-level galvanic isolation and sophisticated signal conditioning, it ensures that low-voltage thermocouple signals remain accurate and free from the electromagnetic interference (EMI) typical of turbine enclosures and heavy engine rooms. This board is essential for maintaining safe operating envelopes through real-time exhaust gas temperature (EGT) monitoring and bearing temperature supervision.
