IS200SAMBH1A is an Acoustic Monitoring terminal board and is part of the GE Speedtronic Mark VI gas turbine control. The twin terminal board adds eighteen inputs to the Acoustic monitoring system via thirty-six terminals on terminal strips for a two-wire input connection. There are also terminal strips on the board with 36 terminal connections set aside for the installation of two-wire buffered outputs, totaling eighteen outputs. Typically, these outputs are used to monitor voltage signals. To defend against externally sourced high-frequency noise, the IS200SAMBH1A is equipped with passive electromagnetic interference (EMI) filters.
