The second panel contains the I/O (input/output) The fourth panel includes all of the bridge control moules
modules. The standard upgrade kit has three (3) digital I/O that perform the firing function. The number of bridge
modules and one (1) analog input/output module. Each control modules depends on how many SCR power drawers
ECM-2 controller has its own set of digital and analog I/O are included in the system. Each SCR power drawer requires
boards (Fig. 4). a bridge control module (Fig. 6).
The third panel consists of the AC and DC transducers, The DECS-2100 front-end retrofit is also supplied with
along with associated power supplies and control transform- an IDP-1200 Interactive Display Panel (Fig. 7). The IDP-1200
ers. This chassis also contains an integrated ground detector has a high-resolution, 12.1 inch (30.7 cm) color touchscreen
relay for rotor field protection (Fig. 5). which provides control, metering, alarm, and graphical
screens. This gives the IDP-1200 more flexibility and features
than the annunciation panel on WDR-2000 systems.

• Automatic synchronizing As this application note has shown, Basler Electric offers
• Auto-tuning cost-effective upgrade solutions for aging WDR-2000 systems.
• Programmable input/output terminations A DECS-2100 front-end retrofit is a viable solution when:
• IRIG-B time synchronization • Available space won’t accommodate the equipment of an
• Communication entirely-new system.
o Multi-port Ethernet • The WDR-2000 logic modules are obsolete but the power
o USB bridges are still intact.
o Fiber optics for bridge firing • Funds aren’t available for a full system upgrade.
