About the IS205TFBHG1A
The IS205TFBHG1A is a Temperature Feedback Board and is one of several sub-assembly boards for the IS200PICHG#A board. The IS205TFBHG1A has a 39-pin connector (backplane) that is used to solder the board to the main board assembly. The board has two temperature feedback channels that are used to monitor IGBT cold-plate temperature. These temperature signals are converted and multiplexed by the IS205TFBHG1A PCB into a serial data stream that is continuously transmitted to the BICH board using a fiber optic cable. This information alternates between the two channels. The IS205TFBHG1A is designed with:
- twenty-four resistors
- twelve capacitors
- five integrated circuits
- a PROM
- an oscillating chip
- a backplane connector (previously mentioned.)
The board is designed without TP test points or jumpers. The board is marked with codes SEC-6-0, 4112, and 6BA01. More information about the IS205TFBHG1A can be found through publications from the original equipment manufacturer, including data sheets, manuals, and user guides.
