IS200DSCBH1AAA is a DIN-Rail Mounted Serial Communications 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 DSCBH1AAA board is a compact interface terminal board, designed for DIN-rail mounting. DSCB connects to the Serial Communications Board (VSCA) with a 37- wire cable. VSCA provides communication interfaces with external devices, using RS-232C, RS422, and RS485 serial communications. The associated DSCB is wired to the external devices, which include intelligent pressure sensors such as the smart Pressure Transducers and Electric Drives used for valve actuation.
The DSCBH1AAA board is held in a plastic frame, which mounts on a vertical DIN-rail. High-density Euro-Block type terminal blocks are permanently mounted to the board, with two screw connections for the ground connection (SCOM). Wiring to the devices uses shielded twisted pair, and communication signals have on-board noise suppression. An on-board ID chip identifies the board to VSCA for system diagnostic purposes.
INSTALLATION:
The wiring connections are to the Euro-Block type terminal block as shown below. There are four terminals for the SCOM (ground) connection, which should be as short as possible. Jumpers J1 - J6 direct SIGRET either directly to SCOM or through a capacitor to SCOM. The shield must be grounded at one end or the other, but not both. If the shield is grounded at the device end, the jumpers should be set to include the capacitor in the circuit. If the shield is not grounded at the device end, the jumpers should be set to go directly to SCOM.
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.

What is GE IS200DSCBH1AAA?
GE IS200DSCBH1AAA is a DIN-rail-mounted Serial Communication I/O Terminal Board used in the GE Mark VI gas turbine control system. It provides the field wiring interface between the VSCA Serial Communications Board and external serial communication devices.
What serial communication interfaces are associated with the I/O Terminal Board?
It is used with the VSCA Serial Communications Board, which supports RS-232C, RS-422, and RS-485 communication interfaces. The DSCB provides the field termination and wiring interface for these communication signals.
How does SCBH1AAA connect to the VSCA board?
The terminal board connects to the VSCA board through a 37-wire cable. The DSCB is installed near the field devices and provides terminal connections for the associated serial communication wiring.
What types of field devices can be connected through the I/O Terminal Board?
The DSCBH1AAA can interface with external intelligent devices that use supported serial communication protocols. Typical applications described for the Mark VI system include smart pressure transducers and Electric Drives used for valve actuation.
What is the purpose of the jumpers on the I/O Terminal Board?
Each of the six channels has a jumper that determines how the cable shield is connected to SCOM ground. The jumper can connect the shield directly to SCOM or through a capacitor, depending on the grounding arrangement at the connected field device.
How should the cable shield be grounded on IS200DSCBH1AAA?
The shield should be grounded at only one end of the cable to help prevent ground-loop problems. When the shield is grounded at the device end, the DSCB jumper is configured to connect the shield to SCOM through the capacitor.
