IS220PDIOH1A is a digital input/output (I/O) module in the Mark VIe series control system produced by General Electric (GE)

1、 Product Overview

Brand and Series: IS220PDIOH1A is an important component of the Mark VIe series control system produced by General Electric (GE).

Functional positioning: As a digital input/output module, it is mainly used to collect various digital signals from the field (such as switch signals, discrete signals, etc.),

And convert it into a digital signal recognizable by the control system. At the same time, it can also output digital signals from the control system to external devices to achieve control of the equipment.

2、 Main functional features

System automatic recognition: The module type can be automatically recognized by the system, achieving plug and play functionality and simplifying the installation and configuration process.

Optoelectronic isolation: Optoelectronic isolation is used between the on-site signal and the system, with an isolation voltage of 1500V, effectively preventing the impact of on-site interference on the system.

Channel isolation: Isolation is also achieved between channels to ensure that a channel failure will not affect the normal operation of other channels.

Independent power supply: The system distribution adopts a+24V power supply that is independent of the system power supply, further ensuring the stability and reliability of the system.

Overcurrent protection: The module itself has overcurrent protection function. When the current input is too large due to its own fault, it has self-protection function. After troubleshooting, the module can resume normal operation.

Data output read back confirmation: The DO channel adopts a data output read back confirmation method to ensure the reliability of data output.

Flexible configuration: Supports multiple configuration methods, such as multiple redundant combinations of single and double, configuring redundancy schemes on a module by module basis to meet the needs of different application scenarios.

3、 Technical specifications

Digital I/O: Provides multiple digital input and output channels, with specific quantities depending on the model and configuration.

Modular design: Modular structure for easy installation and maintenance.

High reliability: Industrial grade components are used to ensure stable operation in harsh environments.

Strong compatibility: seamlessly integrated with GE Mark VI control system, supporting multiple communication protocols.

Working temperature: 0 to 60 ° C, suitable for various industrial environments.

Size and Weight: The dimensions are 15.875 centimeters high x 10.795 centimeters wide, and the weight is approximately 0.8KG (although there may be slight differences in data from different sources, all indicate that it is compact in size and lightweight).
