Product Description

The IS220PTURH1A is a robust and versatile I/O pack designed for use in gas turbine control systems. It features a black outer shell with air circulation holes to ensure optimal thermal management. The front panel includes multiple LED indicators for status monitoring and an infrared port, although the latter is not utilized in this configuration. Internally, the pack houses a CPU board, a dedicated turbine control board, and an analog acquisition auxiliary board, all working in unison to deliver precise control and monitoring capabilities.

The pack connects to the TTURH1C terminal board and supports two 10/100 Ethernet ports for network connectivity. It also includes flash memory, RAM, an identification chip, and a reset circuit. The IS220PTURH1A is equipped with four passive magnetic speed inputs, capable of detecting speeds as low as 2 RPM, ensuring accurate monitoring of turbine rotation. The median speed signal is used for speed control and serves as the primary overspeed trip signal, enhancing the safety and reliability of the turbine system.
