Functional Characteristics

Variability in Configuration: GE IS220PDIAH1A accepts various kinds of discrete contact input terminal boards like TBCI boards, TICI boards, and STCI boards, offering users a higher degree of flexibility and choice in configuration according to specific application requirements.

Easy Installation and Operation: GE IS220PDIAH1A is easy to install and reasonably implements the periodic table. With a convenient and reliable mechanical fixation, it can be easily installed and plugged into the corresponding terminal board connectors. The power input connector with a soft-start circuit can limit the inrush current and reduce the influence to the power supply at startup.

Input Isolation and Filtering: Optical isolation of 1500V on all input; isolation prevents internal interference and damage. The internal hardware filter with 4ms filtering time can filter high-frequency noise and interference signal in the input, so as to improve the input signal accuracy and stability.

Fault Diagnosis

System Monitoring and Alarm: It generally has perfect system monitoring and alarm function in distribution turbine control system of GE Mark VIe series. It is capable of monitoring the status of GE IS220PDIAH1A in the operation. When a fault occurs, the system can issue the corresponding alarm message and diagnostic report, and give the operator a prompt through the HMI or other means, so that the operator can take timely measures to handle the fault.

Serial Communications Diagnostic: The infrared serial communications port enables user local diagnostic serial communications. Users connect to the module through the dedicated diagnostic tool, and the module will be peered using the serial port to obtain rich diagnostic information, such as processor, memory, input channel status and so on, which helps to quickly locate and solve the problem.

Application Fields

Power Generation Industry: GE IS220PDIAH1A is widely used in gas, steam, and wind turbine control systems in the power generation industry, such as the Mark VIe series distributed turbine control system. It can accurately collect the information and processing of each switch point to various sensors in the turbine, accurately reflecting the on-off status of valves, the running status of pumps, and the alarm signals of various protection devices, etc., and ensuring safe and stable operation of the turbine.

Industrial Automation: In industrial automation production lines such as chemical, pharmaceutical, food and beverage and other industries, GE IS220PDIAH1A can be used to connect various discrete devices such as proximity switch limit switch and solenoid valve to realize the monitoring and control of production process. For instance, it can monitor and control the opening and closing of the conveyor belt, the operation of the robotic arm, and the filling status of the packaging machine, as well as the equipment start and stop and the process flow switching.

HVAC Systems: GE IS220PDIAH1A  can be utilized in heating, ventilation and air conditioning systems to monitor the status of a variety of discrete components, including the running status of fans, pumps and compressors, and the opening and closing status of dampers and valves. By accessing and processing these discrete input signals, system can recognize the situation of the environment so as to adjust the operational mode of the HVAC facilities appropriately and timely to realize the energy saving and comfort.
