Product Description
The IS220PIOAH1A is a dedicated communication interface I/O pack module designed for integration into GE’s Mark VIe I/O architecture. This pack functions as a bridge between the field‑device network (such as excitation control, ARCNET, RS‑485) and the main I/O Ethernet network of the control rack. It enables real‑time signal transfer, diagnostic feedback, and communication redundancy.
With dual Ethernet ports, front‑panel LEDs for status indication, and rugged design tolerances, the module is engineered for industrial automation and turbine control applications. It mounts onto a dedicated terminal board and offers the flexibility to integrate legacy networks or field buses into a modern distributed I/O architecture.
Applications
-
Field network interface for excitation control, where ARCNET or RS‑485 networks must connect to the Mark VIe system.
-
Turbine control systems (gas or steam) requiring a communication bridge between field controllers and main rack I/O Ethernet network.
-
Industrial process automation systems where a legacy communication bus must be integrated into a distributed I/O system.
-
Retrofit/upgrades of existing control racks where newer distributed architectures are being implemented, enabling existing field networks to remain in use.
-
High‑availability systems requiring network redundancy and robust communication links between field devices and main controllers.
Advantages
-
Flexible communication bridging – allows legacy field networks (ARCNET/RS‑485) to interface with modern I/O Ethernet architecture.
-
Dual Ethernet ports – supports network redundancy or separation of control/monitor traffic, improving system uptime.
-
Compact and lightweight – approx. 0.8 kg and moderate physical size make installation or retrofit manageable.
-
Industrial‑grade tolerance – suitable for –30 °C to +65 °C ambient environments and designed for rugged control cabinets.
-
Standard plug‑in I/O pack format – simplifies replacement, spare management, and maintenance.
-
Diagnostic support – front‑panel status LEDs, infrared or serial diagnostics help rapidly identify issues.
-
Integration ready – built to fit the Mark VIe I/O rack and network architecture, reducing engineering overhead.
-
Extend system life – enables reuse of existing field buses while upgrading the main control architecture, saving cost and time.
