Core Technical Specifications

DS200PLIBG1A DS200PLIBG1ACA terminates phase logic signals for GE Mark V turbine systems. This termination board measures 26.5 cm in width and 20.0 cm in depth. The unit weighs approximately 0.82 kg without any attached cables. You will find 40 screw-type terminal blocks on this assembly. Each terminal accepts wires ranging from 14 to 22 AWG. The board includes 32 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 65 mA during normal operation.

Component Layout and Energy Storage

The PCB uses a four-layer design for reliable signal routing. Four onboard LEDs indicate termination and power status at key points. DS200PLIBG1A DS200PLIBG1ACA 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 line noise. Accordingly, the board tolerates signal reflections up to 7%. Three DIP switches let you configure termination impedance values. The operating temperature range spans -10°C to 55°C. Meanwhile, humidity tolerance reaches 90% without any condensation forming.

Interface and Mechanical Details

Four mounting brackets securely hold the board to standard racks. DS200PLIBG1A DS200PLIBG1ACA offers 300 V isolation between signal groups. Each termination channel 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 10 minutes during routine maintenance.
