I/O modules

Core Technical Specifications

DS200PTBAG1B DS200PTBAG1BAA terminates analog I/O signals for GE Mark V turbine controls. This termination board measures 27.0 cm in width and 22.0 cm in depth. The unit weighs approximately 0.92 kg without any attached cables. You will find 32 screw-type terminal blocks on this assembly. Each terminal accepts wires ranging from 12 to 22 AWG. The board includes 28 resistor components for signal conditioning. Six of these resistors handle precision voltage division tasks. For power input, the board requires 24 V DC from an external source. It draws roughly 80 mA during normal operation.

Component Layout and Energy Storage

The PCB uses a dual-layer design for straightforward signal routing. Four onboard LEDs indicate power and signal activity at key points. DS200PTBAG1B DS200PTBAG1BAA features two 20-pin header connectors for backplane links. Regarding energy storage, the board contains eight ceramic capacitors. Each capacitor stores 0.22 µF at 50 V. This configuration effectively filters low-frequency power noise. Accordingly, the board tolerates supply ripple up to 5%. Two DIP switches let you configure channel termination settings. 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. DS200PTBAG1B DS200PTBAG1BAA offers 500 V isolation between field and logic sides. Each termination channel supports up to 20 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.
