GE IS200DAMAG1BCB | Gate driver amplifier/interface board

GE IS200DAMAG1BCB has two core designations: one is Gate Drive Amplifier/Interface Board, and it is also referred to as RST Analog I/O Board. This product belongs to GE's Mark VI Speedtronic series (also marked as Mark V series in some documents) and is mainly used for the control of gas turbines or steam industrial systems, serving as a core component of GE's innovative series low-voltage 620-frame drive system.

The following is a summary of the product's core technical data and functional parameters:

Core Functions

Acting as the gate drive amplifier for IGBT modules, it connects the upper and lower phase-leg IGBTs (usually of CM 1000 HA-28 H Power Rex model) and communicates with the Bridge Personality Interface Board (BPIA).

It scales and conditions analog signals in the gas turbine control system, covering signal types such as LVDT input, servo valve output, thermocouple input, 4-20mA input/output, and vibration input.

Hardware Specifications

Equipped with two connectors (12-pin vertical connector + 6-pin vertical connector) for signal transmission and device connection.

Includes 4 LED indicators (2 green, 2 yellow), where yellow indicates the IGBT on-state and green indicates the off-state.

Hardware jumper configuration: J1/J2 for selecting mA output circuits, J5/J6 for configuring the mA output current range (20mA or 200mA), J7 for RS232 port card testing, and J8 for starting the oscillator.

Compatible Systems

Compatible with GE Mark VI Speedtronic gas/steam turbine control systems and 620-frame low-voltage drive systems.

Works in conjunction with IGBT modules, and each drive typically requires 3 such boards.

Electrical Parameters

Power supply input: +15V/-7.5V.

Drive monitoring: 4-channel drive monitoring (UON, UFF, LON, LFF).
