The GE part number IS200DTRTH1A is a Din Rail Terminal Board Transition. It’s a key component of GE’s Mark VI and Mark VIe Speedtronic turbine control systems. Its primary function is to serve as a wiring interface for a large number of signals, providing a clean and organized way to connect field wiring to a main processor board. 🔌
Function and Key Features
A transition terminal board is a passive wiring component that facilitates the connection between the discrete wires from sensors and actuators in the field and the ribbon cables or other high-density connectors used by the control boards.
- Wiring Interface: The board provides screw terminals or other connection points where technicians can connect the individual field wires. This is much simpler and more robust than trying to wire directly to the delicate pins of a circuit board.
- Transition Function: The board “transitions” the signals from the field wiring to a more compact connector, typically a ribbon cable. This allows a single cable to carry a large number of signals to the main processor board, simplifying the system’s wiring and reducing the chance of error.
- Din Rail Mounting: The board is designed to be mounted on a standard Din rail, a metal rail used for mounting industrial control equipment inside a cabinet. This ensures a secure and organized installation.
- System Integration: The DTRT board connects directly to a main control board in the Mark VI or Mark VIe system. It is a passive board and does not contain any active electronics or logic.
- Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant.
Applications
The IS200DTRTH1A 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 inputs and outputs used for turbine control and protection.
- Maintenance: It makes maintenance and troubleshooting much easier by providing clearly labeled connection points that are physically separate from the active electronics.
