GE IS200SRTDH2ABB Mark VI RTD Terminal Board

The GE IS200SRTDH2ABB is an RTD (Resistance Temperature Detector) terminal board designed for the GE Mark VI turbine control system. It provides the field wiring interface for RTD temperature signals, connecting temperature sensor circuits to the associated control hardware. The board is a printed circuit board assembly with two terminal blocks and 36 field connection terminals.

Functional Description

The IS200SRTDH2ABB provides a termination point for RTD sensor wiring within the Mark VI control architecture. RTD sensors measure temperature through changes in electrical resistance. The associated RTD input hardware processes these signals for use by the turbine control system.

The terminal board serves as the field connection interface rather than independently performing the complete temperature measurement and processing function. Correct identification of the associated input hardware and terminal assignments is necessary when replacing or reconnecting the board.

Terminal Configuration

The board has two terminal blocks, with 18 terminals per block and 36 terminals in total. These connections provide the physical interface for field wiring.

Before reconnecting an existing installation, verify the terminal assignments against the applicable Mark VI wiring diagram. Terminal numbering alone does not establish the sensor channel allocation or RTD wiring configuration.
