Description

The General Electric IS220PDIOH1A is a high-performance Discrete I/O Pack designed for the Mark VIe Speedtronic turbine control system. This module serves as a critical interface between the I/O Ethernet networks and the associated discrete input/output terminal boards. It is engineered to provide reliable real-time data acquisition and relay control for industrial turbine management, including steam, gas, and wind turbine applications.

Features

• System Compatibility: Designed specifically for the GE Mark VIe control platform.
• I/O Capacity: Supports 24 contact inputs and 12 Form C mechanical relay outputs.
• Communication: Features dual 100MB Ethernet ports for redundant network connectivity.
• Hazardous Location Support: Approved for use in hazardous environments (Ex ic nA [ic] IIC T4 Gc) when paired with compatible terminal boards such as the IS200TDBSH2A and IS200TDBTH2A.
• Diagnostics: Integrated front-panel LED indicators for Ethernet status, power, and attention (attn) alerts.

Technical Specifications

Installation Guidelines

• Mounting: Secure the compatible terminal board to the cabinet frame before seating the PDIO pack into the designated connectors.
• Handling: Use caution when inserting the module to avoid applying excessive force to the DC-62 pin connector.
• Connectivity: Connect RJ45 Ethernet cables to the ENET1 and ENET2 ports as required by the system architecture (e.g., R controller).
• Power: Connect the 3-pin power supply; the module includes integrated soft-start functionality to manage inrush current.
• Environment: Ensure the installation site meets the environmental ratings specified for the Mark VIe series to maintain hazardous location compliance.

FAQs

What is the primary function of the IS220PDIOH1A?

The IS220PDIOH1A acts as an interface module that bridges the gap between the I/O Ethernet network and field-level discrete devices, managing up to 24 inputs and 12 relay outputs for turbine control.

Can this module be used in hazardous locations?

Yes, the IS220PDIOH1A is approved for use in hazardous locations when installed in accordance with GE documentation and paired with approved terminal boards like the IS200TDBSH2A or IS200TDBTH2A.

What does the front panel LED array indicate?

The LEDs provide visual status for the two Ethernet ports, the unit's power supply status, and an 'attn' (attention) LED for system diagnostics, along with indicators for relay channel status.
