Functional Description
IS230SNCIH6A is a Digital Input Module developed by General Electric. It is a part of Mark VIe series. I/O modules are made up of three basic components: the terminal board, the terminal block, and the I/O pack. The terminal board attaches to the cabinet and is available in two basic configurations: S and T. The S-type board has a single set of screws for each I/O point and can condition and digitize the signal with a single I/O pack. Using one, two, or three boards, this board is used for simplex, dual, and dedicated triple modular redundant (TMR) inputs. Typically, the T-type TMR board fans the inputs to three separate I/O packs. The outputs from the three I/O packs are usually voted on by the T-type board hardware.
System I/O pack details
The system I/O packs in the Mark VIe system consist of two main components: a generic processor board and a data acquisition board that is specific to the connected device. These I/O packs play a crucial role in digitizing signals, running algorithms, and communicating with the Mark VIe controller.
Each terminal board’s I/O pack is responsible for converting analog or digital signals into a digital format that can be processed by the controller. It also runs specialized algorithms to perform specific functions based on the connected device’s requirements. Communication between the I/O pack and the Mark VIe controller enables seamless data exchange and facilitates efficient control of the industrial process.
The I/O pack incorporates special circuitry in the data acquisition board, along with software running on the CPU board, to detect faults. By combining hardware and software mechanisms, the I/O pack can identify and report any anomalies or faults that occur within the connected device. The controller receives and processes these fault status notifications, enabling prompt action and troubleshooting.
During operation, each I/O pack can send an identification message to the main controller when prompted. This message contains essential information about the I/O board, including its hardware catalog number, hardware revision, board barcode serial number, firmware catalog number, and firmware version. This identification data assists in accurately identifying and managing the I/O packs within the system.
The processor board and data acquisition board of the I/O pack are designed to operate within a temperature range of -30°C to 65°C. These components are equipped with free convection cooling mechanisms, ensuring reliable performance even in demanding environmental conditions.(https://www.weikunfadacai1.com/)
Temperature sensors are integrated into the I/O packs to monitor the temperature levels. These sensors are accurate within a 2°C range, providing reliable temperature data. The temperature readings of each I/O pack are stored in the system’s database and can be utilized to trigger alarms or alerts if temperature thresholds are exceeded, allowing for proactive maintenance and preventing potential issues.
System Power Requirements
The Mark VIe control cabinet is designed to be powered by various sources, providing flexibility to accommodate different installation requirements. Before entering the Mark VIe enclosure, each power input source, whether it is a DC or AC source, must pass through its own external 30 A two-pole thermal magnetic circuit breaker. These breakers are essential for ensuring proper protection and compliance with site codes and regulations.(https://www.weikunfadacai1.com/)
For the operation of the control electronics, the input power is converted to 28 V DC. This 28 V DC power is then distributed as needed for various tasks, such as I/O signal processing. Additionally, it is important to consider the current draw of external solenoids when calculating the total current requirements. The documentation provides specific notes and guidelines on how to factor in the current supplied to external solenoids, ensuring an accurate assessment of the power needs.(https://www.weikunfadacai1.com/)
