GE IS220PTURH1B Mark VI Primary Trip I/O Pack for Turbine Control
Product Introduction
The IS220PTURH1B from General Electric belongs to the Mark VI series. GE designed this I/O pack to control and protect gas and steam turbines. Specifically, it regulates HRSG (boiler) systems and auxiliary plant controls. The IS220PTURH1B interfaces with motor-operated valves and other balance-of-plant devices. You will find this module in combined cycle power plants as part of the DCS and turbine control systems.
Technical Specifications
The IS220PTURH1B delivers reliable primary turbine trip functionality. It requires a power supply voltage of 28.0 V dc nominal, with an acceptable range of 27.4 to 28.6 V dc. The maximum current draw is 0.41 A dc.
For voltage detection inputs, the IS220PTURH1B accepts a range of 16 to 140 V dc. The E-stop input operates between 18 and 140 V dc. Speed inputs accept voltages from -15 to 15 V dc.
Additionally, the E-stop power output provides 28 V dc under open-circuit conditions. The short-circuit current is 17 mA dc. The contact output supports 24 to 28 V dc with a maximum current of 7 A dc.
The IS220PTURH1B pairs with the terminal board IS200TRPAH1A for hazardous location use. For Mark VIeS systems, use IS220YTURS1A or IS220YTURS1B with the IS200TRPAS1A terminal board.

Electrical Characteristics Summary
Frequently Asked Questions (FAQ)
1. What terminal board works with the IS220PTURH1B?
The IS220PTURH1B works with the IS200TRPAH1A terminal board. For hazardous locations, this combination is approved. Do not use other terminal boards unless specified.
2. Can I use the IS220PTURH1B in a Mark VIe system?
Yes. The IS220PTURH1B is cataloged under Mark VIe as well. However, for Mark VIeS safety systems, use the YTUR series modules instead.
3. What is the maximum contact output current of the IS220PTURH1B?
The contact output can handle up to 7 A dc at 24-28 V dc. This allows direct control of valves, contactors, or other moderate-power devices.
4. What voltage range does the IS220PTURH1B accept for speed inputs?
Speed inputs accept voltages from -15 V dc to +15 V dc. Ensure your speed sensors provide signals within this range for accurate reading.
5. Where was the IS220PTURH1B manufactured?
The IS220PTURH1B is manufactured in the United States (US). All original units come from GE's US production facilities.
