FUNCTIONAL DESCRIPTION:
IS200SSCAH1AEC 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 SSCA 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. Only a simplex version of the board is available. High-density Euro-style box-type terminal blocks are used. An onboard ID chip identifies the board to the PSCA I/O pack for system diagnostic purposes. In the Mark VIe systems, 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. Only simplex systems are supported.
INSTALLATION:
The SSCA board is mounted on a DIN rail using a sheet metal carrier and plastic insulator mount. This assembly will also bolt directly into a cabinet. There are two types of Euro-Block terminal blocks available:
The I/O cable shield termination is on an external mounting bracket supplied by the customer or by GE. The chassis ground connection uses E1 and E2 as mounting holes. One of the SCOM terminals (37-48) must be connected to a suitable shield ground.
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 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.
When using RS-422 or RS-485, there is the need to provide a termination resistor at either end of a transmission line. SSCA provides selectable termination resistors for each pair of signal lines. Jumpers JP1A and JP1B apply or remove the termination resistors between signals A-B and C-D. The same function is repeated for each serial communication channel. The default jumper position is to disconnect the termination resistor. The SSCA is marked to show the relationship between the termination jumpers and the serial communication channel signals.

What is a Simplex Serial Communication I/O Terminal Board?
A Simplex Serial Communication I/O Terminal Board is a hardware device used to facilitate serial communication between different electronic components or devices. It typically provides a terminal interface for input and output operations.
How does a Simplex Serial Communication I/O Terminal Board work?
The Simplex Serial Communication I/O Terminal Board works by receiving serial data from one device, processing it if necessary, and then transmitting it to another device. It acts as an intermediary, converting serial data into a format that can be easily interpreted by the connected devices.
What are the common applications of a Simplex Serial Communication I/O Terminal Board?
Common applications include industrial automation, data logging, remote monitoring, and control systems. It can be used in various industries such as manufacturing, telecommunications, transportation, and more.
