About the IS200SSCAH1A

Hardware Tips and Specifications 

The IS200SSCAH1A is a small terminal board with very few components. This minuscule 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 terminal 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 IS200SSCAH1A board has:

• two additional (larger) round cutouts
  • located on the short edges of the board
  • designed to facilitate mounting of the board
• three lines of jumper switches
  • six jumpers per line
• 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. The IS200SSCAH1A part number reveals a bevy of other critical IS200SSCAH1A device details, such as its SSCA functional abbreviation.
