IS200BPVAG1B is a backplane card developed by GE under the Mark VI series. It's a PCB component designed for Speedtronic. The MKVI is the third Speedtronic system to offer triple-redundant controls, with triple-redundant backups on all critical controls and protection parameters. Depending on the size and complexity of the turbine system, many MKVI modules are available in either simplex or triple redundant configuration.
