FUNCTIONAL DESCRIPTION:
IS200DSCBH1AAA is a Simplex Serial Communication I/O Terminal Board manufactured and designed by General Electric and is part of the Mark VI Series used in Speedtronic gas turbine control systems. The Simplex Serial Communication Input/Output (DSCB) terminal board is a compact interface terminal board, designed for DIN-rail mounting. DSCB connects to the VSCA board with a 37-wire cable. VSCA provides communication interfaces with external devices, using RS-232C, RS-422, and RS-485 serial communications. DSCB is wired to external devices, which include intelligent pressure sensors such as the smart Honeywell® Pressure Transducers and Kollmorgen® Electric Drives used for valve actuation.

DSCB is wired to external devices, which include intelligent pressure sensors such as the smart Honeywell Pressure Transducers and Kollmorgen Electric Drives used for valve actuation.
INSTALLATION:
Mount the plastic holder on the DIN rail and slide the DSCB board into place. Connect the wires for the external devices to the Euro-block type terminal block as shown in the following figure. Four terminals are provided for the SCOM (ground) connection, which should be as short as possible. Connect DSCB to VSCA using the 37-pin JA1 connector.
OPERATION:
The three XDSA boards are intermediate distribution boards for the RS-422 multi-drop signals. The pressure transducers plug into ports P1, P2, P3, and P4 on these boards. The following figure shows DSCB using two of the six VSCA channels, Ports 1 and 2, to interface with 12 Honeywell pressure transducers.
CONFIGURATION:
Each of the six channels has a jumper to connect the cable shield to the ground through a capacitor. These are used when the shield is grounded at the device end. The jumper positions are shown in the Installation section. All other configuration is done on the VSCA board and in the toolbox.
