Flex500 Digital Control for Turbines, Engines, or Compressors

The Woodward Flex500 is a new-generation digital control for turbine, engine, and compressor applications, built on a rugged industrial hardware platform with a deterministic real-time operating system. It is available in Front Panel Mount (with integrated HMI) and Rear Panel Mount versions, and can be configured for Simplex or Dual-Redundant operation for critical applications requiring high availability and on-line program changes.

Designed to function as a distributed control system, the Flex500 expands with Woodward RTCnet and LINKnet HT distributed I/O modules, and its four Ethernet and four CAN ports integrate with plant DCS architectures over Modbus TCP, OPC, and CANopen protocols.

  • Certified for hazardous locations (CSA Class I Div 2; ATEX/IECEx Zone 2)
  • Sulfur-resistant conformal coating on all modules
  • Achilles cybersecurity certified
  • Marine type approvals: Lloyd’s Register and DNV-GL

Applications

The Flex500 is purpose-built for prime-mover control and protection. It mounts in a plant control room or in a cabinet next to the machine, and operates from −40 to +70 °C (bulkhead mount).

  • Steam turbines
  • Gas turbines
  • Gas and diesel engines
  • Compressor control and protection
  • Hydro turbines
