Part number: IS220PTURH1B
Manufacturer: General Electric
Product type: I/O Pack
Series: Mark VI

IS220PTURH1B is an I/O package developed by GE under the Mark VI series. The Mark VI is used to regulate HRSG (boiler) and auxiliary equipment controls to effectively control and protect gas and steam turbines.

Several I/O special cards were built to connect power plant balancing devices (such as electric valves), and various modules for controlling power plant operating balance (such as boiler drum level control, etc.) were developed and written. Both Mark VI and Mark VIe are used for DCS and turbine control in combined cycle power plants.

About IS220PTURH1B
The IS220PTURH1B printed circuit board is a PCB developed by GE Energy, a shell company of General Electric, specifically for use in its Mark VI Speedtronic family of turbine control system products. This PTUR abbreviated printed circuit board can be more clearly defined as a turbine-specific main I/O Trip Pack. This I/O Trip Pack is considered a revised PCB because it exists as a modified version of the previously existing IS220PTURH1 printed circuit board. As shown in the “IS220” series label in the personalized product number of the IS220PTURH1B board; This Primary I/O Trip Pack has a special assembly version that should support its revised performance specifications. Before making any final purchase decision on this IS220PTURH1B product, it is absolutely important to realize that it is not a device originally developed with its specific Mark VI series features, as this will be the IS220PTURH1 mother PCB. A single Level B functional product revision of the IS220PTURH1B product is not used.
