Functional Description

IS230SSCA2AG01 is a serial communications terminal board developed by GE. It is a part of the Mark VIe control system.The SSCA board is designed for serial communication within the system, offering versatility and reliability in data exchange. The board supports up to six communication channels, providing ample connectivity options for various system requirements. The PSCA I/O pack in Mark VIe systems interfaces with the SSCA. Connecting via the DC-37 pin connector, the I/O pack communicates with the controller through Ethernet. This configuration exclusively supports simplex systems.

Features

• Signal Configuration: Each communication channel on the board can be flexibly configured for RS-232C, RS-485, or RS-422 signaling. This flexibility allows the board to interface with a wide range of communication protocols and devices, enhancing its compatibility and integration capabilities within various system architectures. Whether the application requires short-distance, low-speed communication (RS-232C), or long-distance, high-speed communication (RS-485 or RS-422), the card can be adapted to meet these needs.
• Simplex Design: Available exclusively in a simplex version. This design simplifies the installation and usage of the board by eliminating the need for complex redundant pathways. Despite its simplicity, the simplex design ensures efficient communication functionality, making it a practical choice for many applications where a single communication path suffices.
• Terminal Blocks: The board utilizes high-density Euro-style box-type terminal blocks for its wiring connections. These terminal blocks provide a secure and organized method for connecting wires, which facilitates straightforward installation and maintenance procedures. The design of these terminal blocks helps to ensure reliable electrical connections and reduces the likelihood of wiring errors during setup or service.
• On-board ID Chip: An integrated ID chip is embedded on the board. This chip plays a crucial role in system diagnostics by identifying the board to the PSCA I/O pack. The presence of this ID chip enhances the system's monitoring and troubleshooting capabilities, allowing for more efficient identification of issues and ensuring that the correct board is recognized within the overall system configuration. This feature is particularly valuable in large or complex systems where accurate component identification is essential for maintenance and repair.

Configuration

• Signal Line Termination (JP1A - JP6A, JP1B - JP6B): These jumpers apply or remove termination resistors between signal lines A and B, and between signal lines C and D, for the six serial communication channels.
• Return Connection Selection (JP1R - JP6R): These jumpers determine whether the return connection has a resistive or capacitive connection to SCOM.

Installation

• Mounting: Secure the SSCA board on a DIN-rail using a sheet metal carrier and plastic insulator mount. This setup does not include a shield termination strip.
• Wiring: Utilize 18 AWG wiring, typically shielded twisted pair, for connecting the SSCA board. Ensure proper termination of the I/O cable shield, either using an external mounting bracket provided by the customer or by GE.
• Chassis Ground Connection: Utilize mounting holes E1 and E2 for the chassis ground connection. It's essential to connect one of the SCOM terminals (37-48) to a suitable shield ground for effective grounding.

Frequently Asked Questions

What is IS230SSCA2AG01?
It is a serial communications terminal board developed by GE under the Mark VIe series.

What is the purpose of the ID device on the JA connector?
The ID device on the JA connector serves as a read-only chip containing crucial information such as the terminal board's serial number, board type, revision number, and the specific location of the J connector.

How is the ID device interrogated?
The ID device is interrogated by the PSCA I/O pack, which reads the information stored on the chip.

What happens if there is a mismatch between the ID device and the I/O processor?
In the event of a mismatch between the information retrieved from the ID device and the expectations of the I/O processor, a hardware incompatibility fault is generated.

What does a hardware incompatibility fault signify?
A hardware incompatibility fault indicates that there is a discrepancy between the expected hardware configuration, as defined by the information stored on the ID device, and the actual hardware present in the system.
