Product Description
The IS200SSCAH1A is a PCB component created by the General Electric company for their Speedtronic Mark VI system. The Speedtronic line was created to deliver efficient and reliable management for heavy-duty gas and steam turbines. The Mark VI, which is one of the last of these systems, continues that tradition with its integrated hardware and software that provides a whole system solution for control, protection, and monitoring. This model of IS200SSCAH1A PCB is well-summarized by its functional acronym SSCA, which describes the part as a Serial Communication I/O Terminal Board.
Hardware Tips and Specifications
The IS200SSCAH1A is a small terminal board with very few components. This miniscule board may be bolted directly into a cabinet. One long edge of the board is populated by a single cable connector with 37 (female) connections. The board’s single integrated circuit (U1) is placed to the right of this component. This is a read-only chip, which is not considered programmable. On the longe edge opposite from this board's singular integrated circuit, the board has a single 48-position terminal block. This is a permanently-mounted teminal block. Be extra careful to not confuse the IS200SSCAH1A with its sister model IS200SSCAH2A, as the H2 version features a different, right-angled header for terminal connections. Used to terminate or secure wire connections easily, the terminal block uses screw connections to connect to wires. Two drilled holes with conductive material around their circumference are placed one on either side of the terminal block, to act as terminal connectors. The board has two additional (larger) round cutouts located on the short edges of the board, also designed to facilitate mounting of the board.
The center of the IS200SSCAH1A is populated by three lines of jumper switches, six jumpers per line, along with lines of capacitors and resistors. The jumpers are separated into a square labeled ‘GND’ (one line of jumpers,) and one labeled ‘Termination,’ (two lines of jumpers.) The board is marked with several pieces of information placed on the board in chart form. It also has codes for id, and the manufacturer’s logo. More information on the IS200SSCAH1A may be found through publications like manuals or datasheets from the original manufacturer General Electric.
When used in conjunction with RS-485 or with RS-422, it is crucial to provide a termination resistor at either start of the transmission line. This process should be supported by the IS200SSCAH1A's programmable termination resistors, which are toggled by JP1A and JP1B.
