Product Description:
The IS200ECTBG1ABB is a board component within the Mark VI Speedtronic system from General Electric. This system was designed and distributed by GE for the management of gas and steam industrial turbine systems.
The IS200ECTBG1ABB functions to support excitation contact inputs and outputs. There are two basic versions of the ECTB board: the G1 board, which is used only in TMR systems, and the G2 board, which is used in simplex systems. Both boards are designed with two trip contact outputs for a customer lockout feature, as well as four Form C (general purpose) relay contact outputs. These contacts are typically controlled by the connected EMIO circuit board. The board also has a 52G and 86 G contact input that are monitored and powered by the ECTB board, along with four additional contacts. Power for the IS200ECTBG1ABB board is received from M1 and M2 power supplies.
