Description

Details

The IS200BICLH1 developed by General Electric is a component for the Mark VI series and is apart of the Speedtronic series for gas/steam turbine management. It functions primarily as a Bridge Interface Board between Bridge Personality Interface boards (BPIA/BPIB/SCNV) and the Innovation Series Drive main control board. It features ambient temperature monitoring and a fan pulse width modulated speed control interface and mounts into a VME type rack and connects via two backplane connectors.

The IS200BICLH1 has a narrow front faceplate that includes the board ID, the GE logo and a single opening. The board should be installed in slot 5 and while the board does not include any kind of LED indicators, fuses, test points or adjustable hardware the board does include four RTD (resistance thermal detector) sensor inputs as well as a serial 1024-bit memory device. The board also has four relays, which are used for several functions.

The IS200BICLH1A is an IGBT Drive/Source Bridge Interface Board (BICL) created by GE for the Innovation Series.

The purpose of the IS200BICLH1A is to play a go-between an Innovation Series Drive and the Bridge Personality Interface Boards (BPIA, BPIB, or SCNV), being a primary interface between them. This board has the ability to monitor ambient and bridge temperatures. It has an interface with a PWM speed control and a system fault display. This board has a 1024-bit serial memory that is usually equipped with information about the board’s revision and identification.

The IS200BICLH1A has a nearly blank faceplate with a label that has “Install in Slot 5 Only” written on it. There are two brackets on the faceplate that can help install and remove the card from a VME type rack.

Next to the brackets are two screws that help to further secure the card to the rack. There are many internal components on the actual PCB though. There are 73 resistors, 31 capacitors, 3 diodes, 15 integrated circuits, 4 relays, a metal oxide varistor, and 3 transistors. On the right edge of the board are two P1 and P2 pin connectors that connect the IS200BICLH1A to a card rack assembly.
