PRODUCT INFORMATION
Product Overview
The General Electric IS220PTURH1A is a PTUR Turbine Specific Primary Trip Module for the Mark VI / Mark VIe series. This I/O pack links a turbine control terminal board to one or two Ethernet networks. The assembly contains an internal processor board, a turbine-specific control board, and an analog acquisition auxiliary board. External connections interface through a DC-62 pin connector that mounts directly to an associated terminal board.
The processor section contains two 10/100 Ethernet ports, flash memory, RAM, and an internal temperature sensor. A read-only identification chip and a reset circuit are also incorporated into the board architecture. The front enclosure features LED operational indicators alongside ventilation openings for airflow. The pack integrates with Euro-style terminal blocks and supports Auto-reconfiguration directly from the controller.
