Features:
- Conditions bridge feedback for the DC2000 power and instrumentation path.
- Supports both standard and fast contactor driver interfaces.
- Provides jumper-selectable current attenuation and monitored filter protection.
With
DS200SHVIG1B, bridge sensing and contactor interfacing share one SHVI platform but remain separate circuit functions; measurement conversion does not substitute for the command-driver paths.
Standard and fast contactor commands leave
DS200SHVIG1B through different routes. The fast channel relies on compatible CDAA or CDBA hardware, while the standard path follows its own driver circuit.
The 10:1 current-scaling choice on
DS200SHVIG1B is independent of its three protected filter indications. One sets the measurement ratio; the indicators identify which fused filter path has opened.
The General Electric DS200SHVIG1B SCR High Voltage Interface Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Shunt-to-Frequency Path
- Shunt Range: The interface accepts the documented low-level bipolar current signal.
- Conversion: Conditioning circuits translate that input into differential frequency.
- Transfer: The frequency output travels to the installed supply or instrumentation card.
- Noise Control: Differential signaling supports the bridge-to-control transfer path.
Standard and Fast Outputs
- Standard Driver: An on-board circuit supports the normal contactor path.
- Fast Driver: A separate circuit provides the fast-contactor command path.
- Companion Hardware: Fast operation requires the applicable CDAA or CDBA driver card.
- Path Check: Connector continuity must be verified across both interface stages.
Transformer Ratio Selection
- Jumper Option: Hardware selection enables the documented 10:1 current attenuation.
- Bridge Match: The selected path must correspond to the installed current-transformer circuit.
- Feedback Integrity: A mismatched ratio changes the signal delivered to the control card.
- Record Control: Use the drive-specific hardware summary for the final position.
Physical and Protection Checks
- Standoffs: Six nylon supports secure the board in the cabinet assembly.
- Filter Fuses: Protected voltage-input paths are monitored individually.
- Indicator Action: A lit fuse lamp identifies the corresponding open circuit.
- Clearance: Connector routing must preserve separation from energized bridge conductors.
