GE IS420YDIAS1B Mark VIe Discrete Input Module

GE IS420YDIAS1B Mark VIe Discrete Input Module

The GE IS420YDIAS1B is a rugged discrete input module engineered for critical turbine control applications in power generation and heavy industrial environments. Designed for integration with GE’s Mark VIe and Mark VIeS control systems, this module handles real-time signal acquisition from sensors and safety circuits, ensuring precise monitoring of turbine parameters like vibration, temperature, and rotational speed. Its reliability directly impacts operational safety and system uptime.

Technical Specifications

• Manufacturer: General Electric
• Series: Mark VIe & Mark VIeS
• Model Number: IS420YDIAS1B
• Function: Discrete Input Module
• PCB Protection: S-style coating (enhanced moisture/dust resistance)
• Ports: 3 x industrial-grade connectors
• Indicators: LED diagnostics with labeled faceplate
• Enclosure: Plastic modular housing with front panel

This module excels in environments where turbine reliability is non-negotiable. For instance, a power plant in Texas recently reported zero signal interference issues after upgrading to this module, even during extreme summer heat affecting control room temperatures. The S-style PCB coating proved particularly valuable in offshore oil rigs where saltwater corrosion is a persistent threat.

We routinely stock this component alongside related models like the IS420YDE1S1B and IS420YDOS1B, supporting both new installations and legacy system upgrades. Its compatibility with GE’s Speedtronic architecture makes it a preferred choice for retrofitting older Mark VI systems without compromising diagnostic capabilities.

At ABBOKOK, we’ve maintained a 98% same-day dispatch rate for critical turbine controls since 2018. Our 16 regional warehouses ensure rapid delivery – a client in Norway once received an IS420YDIAS1B replacement within 36 hours during an unplanned turbine shutdown. Every unit comes with our standard 1-year warranty covering both functionality and performance, which we’ve extended twice for this particular model due to its proven reliability.
