MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200GGXAG1A DS200GGXAG1ADB High Voltage Board monitors high potential circuits within drive cabinets. This board senses DC bus voltage and AC line voltage directly. You will find it providing critical feedback to the main drive controller. It ensures safe operation by detecting overvoltage and undervoltage conditions.
Core Technical Specifications
The GE DS200GGXAG1A DS200GGXAG1ADB High Voltage Board measures 20.0 cm in width and 14.0 cm in height. Its board depth equals 2.0 cm including component and connector heights. The total assembly weighs approximately 0.42 kilograms. Six high voltage input channels populate the board’s surface area. Each channel accepts up to 600 VDC or 480 VAC continuous.

Connectors and Input Terminals
The GE DS200GGXAG1A DS200GGXAG1ADB High Voltage Board uses one 20-pin header for analog output signals. This header sends scaled voltage readings to the main processor. Six screw terminal blocks accept high voltage field wiring connections. Each terminal accepts 18 AWG to 14 AWG stranded copper wire. A clear warning label indicates high voltage present on input terminals.
Signal Conditioning and Isolation
This high voltage board scales each input down to 0-10 VDC for the ADC. Precision resistor dividers provide accurate voltage reduction across all channels. Moreover, the GE DS200GGXAG1A DS200GGXAG1ADB High Voltage Board integrates optocoupler isolation on every input channel. This isolation separates the high voltage field side from low voltage logic. A green LED confirms the presence of auxiliary 24 VDC power. Six yellow LEDs illuminate when any input exceeds 80% of its configured range.
Energy Storage and Safety Guidelines
This high voltage board contains small RC snubber networks on each input. Therefore, it stores minimal energy after power disconnection. However, the GE DS200GGXAG1A DS200GGXAG1ADB High Voltage Board connects directly to hazardous potentials. Always disconnect all high voltage sources before handling this board. Wait 5 minutes for external capacitors to discharge completely. Use only insulated tools when working near input terminals. Do not touch the input terminals while the system has power applied. Replace the board immediately if you see any burn marks or cracks.
