FUNCTIONAL DESCRIPTION:

IS200SSCAH2AEC is a Simplex Serial Communication I/O Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Simplex Serial Communication Input/Output (SSCA) terminal board is a compact serial communication terminal board that provides up to six communication channels. Each channel may be configured for RS-232C, RS-485, or RS-422 signaling. The PSCA I/O pack works with the SSCA. The I/O pack plugs into the DC-37 pin connector and communicates with the controller over Ethernet.

INSTALLATION:

Mounting: The board can be mounted on a DIN rail using a sheet metal carrier and plastic insulator mount or bolted directly into a cabinet for enhanced stability.

Terminal Block Options:

SSCAH1: Features a permanently mounted terminal block with 48 terminals, providing a fixed setup for easy installation.

SSCAH2: Equipped with a right-angle header that accepts various pluggable terminal blocks, offering flexibility for different types based on needs or preferences.

Installation: For SSCAH1, the terminal block is permanently mounted. For SSCAH2, attach the pluggable terminal blocks to the right-angle header to ensure a secure connection.

Secure Mounting: After installing the terminal block, ensure the board is securely mounted on the DIN rail or cabinet, providing stable support.

OPERATION:

The SSCA terminal board includes six connection points for each of the six serial communication channels. The points include four signal lines A-D, a signal return, and a shield common (SCOM).

The signals for all six serial communication channels are arranged in the same order. Viewing into the box terminals, the signal order is SCOM, A, B, C, D, Ret viewed left to right. The groups of six signals for a serial channel are assigned to terminals adjacent to each other. Viewing the bottom set of terminals, the channels are five, four, and one viewed left to right. The top set of terminals contains channels six, three, and two viewed left to right. The board SCOM connections are grouped on the right side of the terminals. A simple diagram is included on SSCA to aid in identifying signal locations.

DIAGNOSTICS:

• JA Connector Identification: The JA connector on the terminal board contains a read-only ID device that stores essential information such as the serial number, board type, revision number, and the location of the J connector. This information is retrieved by the PSCA I/O pack for identification purposes.

• Compatibility Check: The I/O processor compares the retrieved data from the ID device with the expected specifications. If a mismatch occurs, it indicates a hardware incompatibility, triggering a fault signal that points to a potential issue with the terminal board's configuration or components.

• Fault Handling: When a hardware incompatibility fault is detected, actions must be taken to resolve the issue. This may include verifying the serial number, revision number, and other details to ensure they align with the expected values. If necessary, the terminal board may need reconfiguration or replacement to restore proper functionality.

FREQUENTLY ASKED QUESTIONS:

What is the JA connector and its function?

The JA connector on the terminal board contains an ID device that stores important data, such as the serial number, board type, revision number, and J connector location. This data is read by the PSCA I/O pack for board identification.

What happens if there is a mismatch between the retrieved ID data and expected specifications?

If a mismatch is found between the retrieved data and expected specifications, the I/O processor will generate a hardware incompatibility fault, indicating a problem with the board’s configuration or components.

How is a hardware incompatibility fault handled?

When a fault is detected, you should verify the serial number, revision number, and other relevant details to ensure they match the expected values. If necessary, the terminal board may need reconfiguration or replacement to resolve the compatibility issue.
