70VV01A is a main control board (MCB) in ABB's HVC series (high voltage controller) or related systems.
Advantages:
- Circuit Breaker/Contactor Control
- Processes local (panel pushbuttons) and remote (from SCADA or DCS systems) operation commands.
- Implements complex interlocking and interlocking logic to ensure safe and correct operation (for example, closing the circuit breaker only when the grounding switch is open).
- Overcurrent Protection
Detects short circuits or severe overloads and triggers a trip.
- Undervoltage Protection
Trips when voltage drops abnormally to protect the load or prevent system failure.
Condition Monitoring and Signal Acquisition: Continuously monitors the status of primary equipment via digital inputs (DIs).
- Communication and Data Upload
-Equipped with a standard serial communication port (such as RS485) or Ethernet interface.
-Supports mainstream industrial communication protocols such as Modbus RTU or Modbus TCP/IP. All collected status information, alarm signals, and measurement data are uploaded to a higher-level monitoring system (such as SCADA) and receive control commands from the higher-level system.
- Self-diagnosis function
Continuously monitors the health of its own hardware and software. When an internal fault (such as memory error, communication interruption, power supply abnormality) is detected, an alarm signal is generated and uploaded, and even control outputs are locked to ensure safety.
Power Supply: 24V DC, 48V DC, or 110/220V DC
Digital Inputs (DI): Quantity: Typically multiple
Type: Typically passive dry contact inputs or high-level DC signals (e.g., 24V DC). Used to connect auxiliary contacts and status sensors.
- Digital Outputs (DO) / Relay Outputs
Quantity: Multiple
Type: Typically relay outputs with sufficient capacity to directly drive trip and closing coils (e.g., 220V AC/DC, 5A). Some passive contact outputs are also available for signal indication.- Analog Inputs (AI)
Quantity: Fewer.
Type: Used to receive signals from voltage transformers (PTs), typically 0-120V AC or 0-240V AC.- Communication Interfaces
- Ethernet (RJ45) interface, supporting Modbus TCP/IP protocol.
- Environmental Conditions
- Storage Temperature: -40°C to +85°C
- Humidity: Meets IEC standards, typically 5% to 95% non-condensing.
