Woodward 8408-921 Single Channel Exciter for Industrial Gas Turbine Ignition System

Description

The Woodward 8408-921 is a single-channel STExcite™ high-energy ignition driver designed for industrial gas turbines, interfacing with ignition leads and igniters to generate high-current ignition pulses for combustion chamber ignition.

Features

  • Digital Signal Processing (DSP): Enables advanced diagnostics, self-testing, and fault detection for reliable operation.
  • Drop-In Replacement: Designed to directly replace existing ignition system drivers in legacy turbine setups.
  • Wide Compatibility: Works with industry-standard igniters and flexible ignition leads (3.0 m to 9.8 m).
  • Safety & Monitoring: Internal fault relay and alarm contact to signal power loss, voltage issues, or ignition failures.
  • Communication Capability: Supports DeviceNet for network integration and remote diagnostics.
  • Hazardous Environment Compliance: Available with CSA certification for Class I, Division 2, Group D locations and CE marking for EMC/Low Voltage directives.
