IS200DRTDH1A is a PCB (printed circuit board) component manufactured by GE as part of its Mark VI Speedtronic system for managing gas and steam turbines. “DRTD” stands for DIN rail resistance temperature detector.

IS200DRTDH1A is an RTD input terminal board. This board is one of several RTD input terminal boards that can be used for Speedtronic Mark VI systems (PRTD, TRTD, SRTD) Many of these boards are compatible with each other. Please note that IS200DRTDH1A is not compatible with regular PRTDH1A boards.

The RTD terminal board serves as a resistance temperature detector. They typically provide current isolation or transient protection for the connected systems. According to the setting and type of the circuit board, RTD can provide single, dual, or TMR control.

IS200DRTDH1A is a DIN rail mounting plate. It is surrounded by DIN rail brackets all around. The circuit board itself is labeled with codes similar to PLC-4, 6DA00, and 6BA01. There is also a barcode attached near one of its short edges. The components of this board are few, but it includes a D-type female connector with screw connections for fixing cable connections, a European two-stage terminal board, an integrated circuit, and two rows of capacitors. This wooden board has holes drilled at both corners.
