Core Technical Specifications

DS200QTBAG1A DS200QTBAG1ACB terminates RST communication signals for GE Mark V turbine controls. This termination board measures 26.5 cm in width and 21.0 cm in depth. The unit weighs approximately 0.85 kg without any attached cables. You will find 24 screw-type terminal blocks on this assembly. Each terminal accepts wires ranging from 14 to 22 AWG. The board includes 16 resistor components for signal conditioning. Four of these resistors handle precision termination duties. For power input, the board requires 5 V DC from the backplane. It draws roughly 70 mA during normal operation.

Component Layout and Energy Storage

The PCB uses a four-layer design for balanced signal integrity. Four onboard LEDs indicate termination status at key points. DS200QTBAG1A DS200QTBAG1ACB features one 16-pin header connector for backplane links. Regarding energy storage, the board contains six ceramic capacitors. Each capacitor stores 0.1 µF at 25 V. This configuration effectively filters high-frequency line noise. Accordingly, the board tolerates signal reflections up to 8%. Two DIP switches let you configure termination impedance settings. The operating temperature range spans -10°C to 55°C. Meanwhile, humidity tolerance reaches 90% without any condensation forming.

Interface and Mechanical Details

Two mounting brackets securely hold the board to standard racks. DS200QTBAG1A DS200QTBAG1ACB offers 300 V isolation between signal groups. Each termination point supports up to 5 mA of current. Transitioning to physical protection, a conformal coating covers all copper traces. This coating effectively resists dust and moisture ingress. You can replace the board in under 10 minutes during routine maintenance.
