✓The next generation 505DR (Dual-Redundant) front panel mount user configurable steam turbine digital governor control single valve and single-extraction and admission with advanced integrated multilingual interface HMI screen.
✓The 505DR builds on the robust and reliable standard setting 505 platform trusted globally with dual-redundancy (Syscon & Backup) control, expanded communication protocols, intelligent/adaptive control algorithms, and advance service tools with data log and RemoteView monitor and control.
✓This model is a high voltage 88-264 Vac or 90-150 Vdc power input and is rated for Class 1, Div.
✓2 standard location.
✓The 505DR® dual-redundant steam turbine control is a state-of-the-art digital control platform designed to reliably control and protect single valve and single-extraction steam turbines with the advantage of dual-redundancy for maximum turbine reliability and availability.
✓Redundancy is managed at the operating system level using Woodward’s RTN (Real Time Network), allowing ultra-fast changeovers and “bumpless” transitions.
✓Driving generators, compressors, turbo-expanders, fans, and pumps.
✓The 505DR is a highly efficient redundant turbine control.
✓It includes the turbine control, system sequencer, operator control panel and first out indicator.
✓This design minimizes external devices and wiring and eases troubleshooting.
✓The 505DR® system assigns one control as System Controller (Syscon) which actively controls the turbine.
✓The second unit is configured as Backup.
✓The system automatically assess the heath of the Syscon and will initiate a fast switchover when a failure occurs.
✓Switchover can also be initiated manually.
✓The system tightly synchronizes software states and memory from the Syscon to the Backup, insuring that control outputs remains steady with no effect on turbine operation (a true “bumpless” transition).
