Product Introduction

The GE IS220PDIAH1BE is an I/O module designed for GE's Mark VIe control system, mainly used for turbine control and monitoring. Here are some of the main functions of the module:
Input and output functions
Input function: The module is able to receive analog and digital signals from various sensors, such as temperature, pressure, flow, vibration and other parameters. After processing, these signals can be used by the Mark VIe control system to monitor the operating status of the turbine.

Output function: The module can output control signals to actuators such as valves, motors, etc. to adjust the operating parameters of the turbine to ensure that it operates in the best state.

Communication function
Ethernet interface: Supports data communication via Ethernet, allowing the module to exchange data with other control systems, monitoring systems or remote terminals.

Monitoring and protection functions
Vibration protection: The module has a vibration protection function and can directly connect vibration protection sensors such as seismic (velocity) type sensors and accelerometers. This helps to monitor the vibration of the turbine in real time and trigger protection measures when necessary.

Tachometer speed tracking filter: Built-in tachometer speed tracking filter is used to isolate the appropriate vibration frequency of each shaft for display, alarm and protection.

Control Function
Servo control: The module supports direct interface with bipolar servo actuators and LVDT valve position feedback for fuel valve and inlet guide vane (IGV) control.

Pulse rate input and feedback: Provide pulse rate input and feedback for servo control loops using liquid fuel flow to ensure accurate flow control.

Stable voltage adaptability
As a GE Mark VIe I/O package, the IS220PDIAH1BE has a nominal rated voltage of 24.0VDC, a maximum rated value of 28.6VDC, and a maximum rated voltage of 32VDC for contact input. This voltage setting can adapt to voltage fluctuations within a certain range, ensuring stable operation of the equipment under different power supply environments and ensuring the reliability of the control system.

Efficient signal processing capability
This module plays an important role in GE turbine control systems, realizing functions such as signal acquisition, processing and transmission, and can digitally process sensor signals and execute related algorithms, efficiently supporting the control and monitoring of various industrial automation equipment.

Certification for multiple locations
UL certified for use in non-hazardous and hazardous locations, and the IS220PDIAH1B is approved for use in hazardous locations, which means it can be safely deployed in a variety of complex and potentially hazardous industrial environments, providing safety protection for applications in different industrial fields such as petroleum, chemical, electric power, and metallurgy.

Strong compatibility
Can be used in combination with various GE terminal boards, such as IS200STCIH1A and 2A, IS200STCIH8A, Is200TBCIH2C or H4C, IS400TBCIH2C, IS400STCIH1A or 2A, or IS400STCIH8A, which are part of the Mark VIe Speedtronic system. This good compatibility allows it to be easily integrated into GE's turbine control system architecture, facilitating system expansion and upgrades.

Replaceability and maintainability
Each I/O package in the system (such as IS220PDIAH1BE) communicates directly on IONet, which enables each I/O package to be replaced individually without affecting any other I/O in the system. In addition, the I/O package can be replaced without disconnecting any field wiring, which greatly improves the convenience of system maintenance, reduces maintenance time and cost, and enhances the maintainability and availability of the entire control system.

Other features
Stable power supply: The module has a stable power supply interface to ensure reliable operation under various working conditions.

Direct interface: Supports direct plug-in interface for easy installation and maintenance.
