IS200WREAS1A - WREA Aero Trip Terminal Board Daughterboard | GE Mark VIeS | B7B

IS200WREAS1A is a General Electric WREA Aero Trip Terminal Board Daughterboard for GE SPEEDTRONIC™ Mark VIeS Safety control systems. The WREA function supports aero-derivative turbine emergency trip protection operation in turbine control and balance-of-plant applications that use the Mark VIeS Terminal Board and I/O Hardware. It should be matched to the installed catalog number, hardware form, and cabinet configuration before it is used as a replacement.

GE documentation identifies the supported point information as 48 points of Aero-derivative Turbine Emergency Trip when used together with a TREAS#A terminal board and the PPRAS1A or PPRAS1B I/O pack (IEC 61508 safety-certified functions). The hardware is documented as a removable, barrier-style terminal board. It should be matched with the compatible TREA terminal board and PPRA protection I/O pack where that pairing is used in the site configuration.

This component is typically considered when troubleshooting Mark VIeS Safety hardware, replacing a failed module, evaluating repair options, or maintaining spare inventory for turbine protection systems. Before installation, verify the catalog number, hardware revision, and associated terminal board or I/O pack configuration against site documentation and OEM requirements. The OEM reference for this listing is GEH-6721 Vol I; GEH-6721 Vol II.
