Core Technical Specifications

DS200QTBAG3A DS200QTBAG3ADC terminates RST signals for GE Mark V turbine control systems. This termination board measures 29.5 cm in width and 23.0 cm in depth. The unit weighs approximately 1.15 kg without any attached cables. You will find 36 screw-type terminal blocks on this assembly. Each terminal accepts wires ranging from 12 to 22 AWG. The board includes 24 resistor components for signal conditioning. Eight of these resistors handle precision voltage division tasks. For power input, the board requires 5 V DC from the backplane. It draws roughly 100 mA during normal operation.

Component Layout and Energy Storage

The PCB uses a six-layer design for superior signal integrity. Six onboard LEDs indicate signal status at each termination point. DS200QTBAG3A DS200QTBAG3ADC features two 20-pin header connectors for backplane links. Regarding energy storage, the board contains ten ceramic capacitors. Each capacitor stores 0.1 µF at 50 V. This configuration effectively filters high-frequency noise from incoming signals. Accordingly, the board tolerates signal ringing up to 10%. Four DIP switches let you configure termination impedance values. The operating temperature range spans -20°C to 65°C. Meanwhile, humidity tolerance reaches 95% without any condensation forming.

Interface and Mechanical Details

Four mounting brackets securely hold the board to standard racks. DS200QTBAG3A DS200QTBAG3ADC offers 500 V isolation between signal groups. Each termination point supports up to 10 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 12 minutes during routine maintenance.
