IS200VRTDH1DAB modular

Description

Product Description
The IS200VRTDH1DAB is a GE Mark VI PCB component. Released by GE under the “Speedtronic” name, the Mark VI is one of a line of steam/gas turbine management systems designed to improve reliability and decrease downtime of heavy-duty turbines. The Mark VI is built with triple-redundant backups on critical controls and includes a central control module that connects to a PC-based HMI (human-machine interface.) This interface allows access to turbine data from one location using specially-designed turbine control software.

The IS200VRTDH1DAB excites Resistance Temperature Devices (RTDs) and captures the resulting signals, which are then converted into digital temperature values. These values are transferred over the VME backplane to the VCMI and to the controller. RTD short and open circuits are detected by out of range values. These ‘outside of hardware limits’ RTDs are removed from scanned inputs in order to prevent adverse effects on other input channels. These out of range RTDs can be reinstated manually or will be reinstated automatically every twenty seconds if they are within range.

A front faceplate is attached to the IS200VRTDH1DAB via three screws. The back edge of the board is populated by two backplane connectors. The IS200VRTDH1DAB has over two hundred integrated circuits, over two hundred capacitors, and several hundred resistors. Some components are located on the rear surface. The board and the faceplate are both marked with the manufacturer’s logo and also carry the board ID number. Codes like “6BA01” and “94V-0” appear on the surface. Please refer to “Mark VI Turbine Control System Guide Vol II” (GEH-6421) for more information on board operation and specifications.
