GE IS200DTAIH1ABB is a simplex analog input/output terminal board IS210DTAOH1AA specially designed for General Electric Mark VI turbine control system series. This series has a long-standing reputation in the field of turbine management. Since the launch of the Speedtronic series in the 1960s, it has undergone multiple iterations. The Mark VI turbine control system, building on the predecessor Mark V, has added wind turbine functional applications focusing on alternative energy, becoming one of General Electric  iconic product series.

Product Features

(1) Protective Coating

The circuit board surface of IS200DTAIH1ABB is covered with a thin conformal coating. Applied through chemical means, this coating provides reliable protection for the entire circuit board, effectively resisting dust, moisture, and other environmental factors that may affect the board's performance. It significantly enhances the product's stability and durability in complex working environments.

(2) Installation Method

Thanks to its plastic mounting base design, the circuit board can be conveniently installed on standard DIN rail assemblies. This installation method not only makes the installation process simple and efficient but also facilitates disassembly and replacement during equipment maintenance or upgrades, offering great convenience to users.

(3) Input and Output Functions

Rich analog inputs: The circuit board is equipped with up to ten analog input channels, which can accurately collect analog signals from various sensors, such as those output by temperature sensors and pressure sensors, providing comprehensive and accurate data support for the turbine control system.

Flexible analog outputs: It has two analog output channels, with a default output range of 0-20mA. Notably, one of the output channels can be flexibly adjusted to a current output range of 0-200mA by reconfiguring the jumpers, to meet the diverse requirements for output signals in different devices and application scenarios.

(4) Electrical Connection Design

37-pin connector: The circuit board is equipped with a 37-pin connector (marked JR1) with locking fasteners. This connector design ensures stability and reliability when connecting to other devices or components, effectively avoiding signal transmission interruptions or data loss caused by loose connections.

Terminal board: It also features a terminal board (TB1) with 48 screw connection points. Typically, shielded twisted-pair wires (of #18 AWG specification) are used to connect to the terminal block to ensure the quality of signal transmission and reduce the impact of external electromagnetic interference on signals. It is particularly important to note that screws 43/44 are designated as the ground (SCOM) connection points. During actual installation and use, the ground wire should be kept as short as possible to reduce ground resistance and improve the system's anti-interference capability and safety.

(5) Jumper Settings

There are a total of twenty-one jumper switches on the circuit board, marked as JP1A/B - JP10A/B (20 in total) and JP0. These jumper switches provide users with flexible circuit configuration methods. Users can adjust the jumper settings according to specific application needs and system requirements to change certain functional characteristics of the circuit board, thereby enabling it to better adapt to different working scenarios.

Appearance and Structure

On the surface of the circuit board, there are 54 square black components, most of which are neatly arranged in parallel. In addition, at the bottom of the circuit board, there are other components arranged in pairs, marked sequentially from D1 to D54. Two small square integrated circuits (labeled U1 and U2) are also visible on the board's surface. Meanwhile, the circuit board is equipped with resistors, multiple small capacitors, and a long connector port on its left edge. Users can connect additional components to the circuit board through this connector port to further expand its functions.

Application Fields

As the GE IS200DTAIH1ABB belongs to the Mark VI turbine control system series, it is mainly applied in the control systems and management systems of GE-compatible gas, wind, and steam turbine automation drive components. In these fields, it can accurately collect and process various analog signals, providing critical data support and signal transmission guarantees for the stable operation, efficient control, and fault diagnosis of turbines. Whether in power plants, industrial production facilities, or other places involving turbine operation, this circuit board plays an indispensable and important role.
