Main Functions

1. Precision Temperature Acquisition: Converts low‑level T/C voltage signals into digital temperature values for combustion control.

2. EGT Monitoring & Protection: Tracks exhaust gas temperature across multiple cylinders/stages; triggers alarms/trips on over‑temp to protect turbines/engines.

3. Thermal Gradient Detection: Identifies uneven heating to avoid thermal stress and mechanical damage.

4. System Integration: Communicates with Woodward control platforms via RS‑485 for data logging and closed‑loop control.

Differences from 5462‑944

• 5462‑944: Speed controller (505 series), for engine/turbine speed/load regulation.

• 5462‑948: Temperature input card, for EGT/thermal monitoring (I/O module, not a controller)。
