GE IS200DTBBH1A Terminal Board,MMV,CI,,Removbl

الوصف

The GE part number IS200DTBBH1A is a Terminal Board used in GE’s Mark VI and Mark VIe series of turbine and generator control systems. Its primary function is to serve as a wiring interface for a variety of signals, including millivolt (MMV) and current inputs (CI), providing a clean and organized connection point to the main processor board. 🔌

Function and Features

A terminal board like this simplifies the complex task of wiring numerous sensors in a power plant. The “DTBB” designation stands for DIN-Rail Terminal Board B.

• Wiring Interface: The board provides screw terminals where technicians can connect field wiring from a variety of sensors. This eliminates the need to wire directly to the control card itself, making installation and maintenance much easier.
• MMV and CI Support: The board is designed to support both MMV (Millivolt) and CI (Current Input) signals. This means it can handle a wide range of low-level analog inputs, such as those from thermocouples (MMV) and current loop devices (CI) used for measuring flow or pressure.
• Removable: The “Removable” designation indicates that the terminal block can be unplugged from the main board without needing to disconnect the field wiring. This is a crucial feature for quick and easy replacement of the control card during maintenance or troubleshooting.
• System Integration: The DTBB board plugs directly into the main Mark VI control board, providing a clean and organized way to manage all the field I/O connections. It may connect to the main board via a ribbon cable.
• Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant.

Applications

The IS200DTBBH1A is used in power generation facilities that operate GE’s Mark VI and Mark VIe turbine control systems. It is an essential component for:

• I/O Management: It simplifies the wiring and management of the large number of millivolt and current signals used for turbine control and protection.
• Maintenance: Its removable design significantly reduces downtime during component replacement, as the field wiring can remain in place.
