VME Interface and System Integration
The GE DS200SIOCG1A DS200SIOCG1ADA connects to standard VME backplanes via a 96-pin DIN connector. This board follows VMEbus specification for reliable system integration. The DS200SIOCG1A DS200SIOCG1ADA acts as a slave device on the VME bus. It responds to standard address and data transfer cycles. The board consumes minimal VME backplane power for operation. Four status LEDs show power, running, I/O activity, and fault conditions.
Analog Input Specifications and Configuration
This VME stand I/O board features eight single-ended analog input channels. Each channel accepts ±10 V or 4-20 mA signals from field sensors. A 12-bit ADC provides 4096 counts of measurement resolution. The GE DS200SIOCG1A DS200SIOCG1ADA scans all inputs sequentially every 20 milliseconds. Input accuracy reaches ±0.5% of full scale at 25°C. You can configure each channel independently through software settings.
Analog and Digital Output Capabilities
Four analog output channels provide ±10 V or 4-20 mA signals. Each output uses a 12-bit DAC for 4096 discrete steps. The DS200SIOCG1A DS200SIOCG1ADA updates outputs every 10 milliseconds. Sixteen digital input channels accept 24 V DC signals from switches. Sixteen digital outputs provide 24 V DC at 0.5 amperes each. Outputs use open-collector transistors for load switching.
Physical Dimensions and Installation Guidelines
The GE DS200SIOCG1A DS200SIOCG1ADA weighs 0.380 kilograms for secure mounting. Its height measures 250mm, width 40mm, and depth 160mm. Install this board in any standard 6U VME card slot. The board consumes 4.5 watts from the VME backplane power supply. It operates reliably from 0°C to +50°C ambient temperature. Use proper ESD handling procedures during installation.
Energy Storage and Filtering Characteristics
The DS200SIOCG1A DS200SIOCG1ADA includes a 220 µF capacitor for power filtering. This capacitor stabilizes the analog and digital voltage rails. It also reduces noise on the analog input circuits. The capacitor discharges within 30 seconds after removing input power. Wait one minute before servicing the GE DS200SIOCG1A DS200SIOCG1ADA for safety. No battery is present on this VME stand I/O board.
