Product Description
The GE IS220PDIAH1A is a Discrete Input Pack from the Mark VI Turbine Control System Series, engineered for reliable digital signal acquisition. It processes discrete contact signals from field devices and integrates them into the Mark VI control architecture.
Moreover, the IS220PDIAH1A enhances turbine control flexibility by supporting gas, steam, and wind turbine applications. This model is a revised version of the IS220PDIAH1, offering improved interface stability and hazardous area compliance. Its compact PCB design allows simple installation within standard GE drive assemblies.
Functional Highlights
- Optimized Input Control: Supports up to 24 discrete input channels with optical isolation up to 1500 V.
- Rugged Design: Operates reliably in extreme conditions from –40 °C to +70 °C.
- Smart Filtering: Built-in 4 ms hardware filtering improves noise rejection and ensures accurate signal reading.
- Ethernet Communication: Dual Ethernet ports (ENet1 and ENet2) simplify diagnostics and system networking.
- Compliance & Safety: Certified for UL 60079-15 Ed. 3 and ATEX Zone 2 Group IIC applications.
- Easy Compatibility: Fully compatible with terminal boards such as IS200TBCIH4C, IS200STCIH1A, and IS200STCIH8A.
In addition, its lightweight 0.8 kg structure and modular terminal configuration simplify both installation and field replacement.
