The IS210DTAIH1A developed by General Electric is a GE component created for the Mark VI system. The Mark VI is a gas/steam turbine management system released under the Speedtronic series. This board is known as a Simplex Analog Input/Output terminal board for analog signals. It is mounted into a plastic holder that allows the PCB to be DIN-rail mounted and features ten analog inputs as well as two analog outputs. The outputs are 0-20mA however one can be configured for 0-200mA current by reconfiguring jumpers. The board is populated with a single 37-pin connector with latching fasteners that is labeled JR1. One terminal board is available with 48 screw connections and is permanently mounted to the board. Shielded #18 AWG wire are typically used in the terminal block and it is important to note that screws 43/44 are designated as the ground (SCOM) connector and this connector should be as short as possible. Additionally, the board has twenty-one jumper switches, various capacitors, resistors and integrated circuits, as well as four small sub-panels.
