IS220YDIAS1A GE Mark VIe

The IS220YDIAS1A is a high-reliability discrete/switching input module (I/O Pack) developed by General Electric for its Mark VIe / Mark VIeS control and functional safety systems. This module is primarily used for acquiring dry-contact and wet-contact switching signals from industrial field devices and is widely used in heavy-duty gas turbines, steam turbines, and large-scale industrial automation control applications.

The module’s core function is to acquire dry-contact switch signals from industrial field environments (such as equipment start/stop status, valve open/close positions, and fault contact signals). It suppresses electromagnetic interference through built-in electrical isolation circuits, converts the signals into digital signals recognizable by the controller, and transmits them to the GE Mark VIe control system.

• Highly Reliable Design: Suitable for harsh industrial environments, with resistance to vibration, humidity, and temperature fluctuations.
• Fast Response Performance: Features a built-in high-speed signal detection circuit with a signal response time of ≤1 ms, enabling precise capture of millisecond-level transient switching signals.
• Flexible Configuration: Each channel has an independent LED status indicator, facilitating quick diagnosis and troubleshooting.
• Advanced Diagnostic Capabilities: The module features comprehensive built-in diagnostic functions that monitor channel status and communication health in real time.
• Safety Certification Assurance: Certified to both UL and CE standards, making it suitable for use in both hazardous and non-hazardous locations.
• Software-Programmable Filtering: Effectively filters out signal glitches caused by strong electromagnetic interference from power plant inverters and motors.

1. Preparation: Check the anti-static packaging of the new module and wear an anti-static wrist strap (ESD Wrist Strap).
2. Alignment: Align the D-Sub high-density connector on the IS220YDIAS1A with the corresponding socket on the terminal board.
3. Securing and Locking: Gently tighten the mounting screws on both sides of the module to ensure good electrical contact and secure locking (avoid over-tightening).
4. Ethernet Cable Connection: Connect the dual-port IONet Ethernet cable to the RJ-45 port on the top of the module.
5. System Configuration: Assign the new module in the ToolboxST configuration software and deploy the configuration file.

In the steam turbine control system of a thermal power plant, the IS220YDIAS1A module is responsible for acquiring discrete signals from various sensors, such as contact signals from temperature switches and pressure switches. These signals reflect the operating status of the equipment, and the module transmits the acquired signals to the control system for analysis and processing.

The module is also capable of regulating the steam turbine's rotational speed and performing tasks such as engaging the brake, automatically determining thermal status, selecting the startup mode, accelerating, and maintaining a constant speed of 3,000 rpm.

How many input channels does the IS220YDIAS1A have?
This module provides 32 discrete input channels.

What types of input signals does the IS220YDIAS1A support?
It supports dry contact (passive contact) and wet contact signals, and is compatible with 24V DC active PNP/NPN signals. The input voltage range is 24V DC to 32V DC.

What is the operating temperature range of the IS220YDIAS1A?
The operating temperature range is -40°C to +85°C.

What is the warranty period for this module?
Typically, the warranty period for original products is 12 months.
