GE IS400TBCIH2C

الوصف

The GE IS220PDIAH1B is a Discrete Input (PDIA) I/O pack for the GE Mark VIe control system. This module is a key component that provides the electrical interface between the controller’s Ethernet network and a discrete input terminal board, allowing the system to monitor on/off signals from field devices.

Functionality and Features

The IS220PDIAH1B is designed to handle discrete contact inputs, also known as “dry-contact” digital inputs. It works by providing a wetting voltage to a contact and then sensing whether the contact is open or closed, giving the system a clear on/off status.

• Signal Interface: The module connects to a discrete input terminal board via a DC-37 pin connector. This terminal board, such as the IS200STCIH1A, performs the initial signal conditioning.
• Input Channels: It accepts up to 24 dry contact voltage input channels, making it a versatile option for monitoring numerous devices.
• Wetting Voltages: The module supports multiple wetting voltages (24 VDC, 48 VDC, or 125 VDC), which are provided to the terminal board. This allows it to be compatible with a wide range of field sensors and switches.
• Connectivity and Redundancy: The I/O pack connects to the system via dual RJ-45 Ethernet ports, supporting both simplex (single) and redundant configurations. This ensures reliable communication and provides fault tolerance.
• Diagnostics: It includes visual diagnostic LEDs to indicate the status of each input. These LEDs turn on when an input is picked up, making troubleshooting and maintenance easier.
• Safety Certifications: The module is often certified for use in hazardous locations, making it suitable for applications in industries like oil and gas, where safety is paramount.
