The GE IS420PUAAH1A is a Universal Input/Output (I/O) Module designed for the Speedtronic™ Mark VIe control system,
providing flexible signal conditioning and interfacing for industrial automation and turbine control applications.
1. Key Functions & Features
Versatile Signal Handling:
Supports universal analog/digital inputs and outputs, configurable for:
Analog Inputs (AI): 4-20mA, 0-10V, RTDs, thermocouples (Type J, K, T, etc.).
Digital Inputs (DI): Dry/wet contact, 24V DC/120V AC signals.
Analog Outputs (AO): 4-20mA or 0-10V for actuator/valve control.
Digital Outputs (DO): Relay or transistor-based (24V DC).
High-Density & Modular Design:
16-channel I/O capacity in a single slot, reducing footprint in control cabinets.
Hot-swappable (with Mark VIe system support) for minimal downtime during maintenance.
Precision & Reliability:
16-bit resolution for analog signals ensures high measurement accuracy.
Built-in galvanic isolation (channel-to-channel and field-to-system) to prevent noise interference.
Seamless Mark VIe Integration:
Communicates via Ethernet (ICM) backplane with Mark VIe controllers for real-time data exchange.
Configurable via ControlST™ Toolkit for parameterization and diagnostics.
2. Applications
Power Generation: Interfaces with sensors/actuators in gas/steam turbines (e.g., pressure, temperature, speed monitoring).
Process Industries: Used in DCS/PLC systems for chemical, oil & gas, and water treatment plants.
