Input:
1.Power Input:
Dual-channel redundant power input, supporting 110V DC / 220V DC (switchable) and 110V AC / 220V AC (optional), input voltage tolerance ±10%, ensuring stable power supply even when the input voltage fluctuates;
equipped with overvoltage and undervoltage protection to prevent damage to the board caused by abnormal input voltage.
2.Signal Input:
4 analog input channels (0–10V DC, 4–20mA) for monitoring power supply parameters such as input voltage, input current, and power consumption;
2 digital input channels for receiving control signals from the main control system, supporting remote on/off control of the power supply board.
3.Communication Input:
Supports industrial communication protocols such as Modbus RTU and Profibus DP, enabling seamless data exchange with ABB UNITROL 5000 excitation system, frequency converters, and SCADA systems, facilitating real-time monitoring of power supply status.
1. Dual-Channel Redundant Design: Adopts dual-channel redundant power input and output design, ensuring continuous power supply even if one channel fails, greatly improving the reliability and stability of the power supply system.
2. Versatile Power Input/Output: Supports multiple input voltage types (DC/AC switchable) and stable dual-channel 24V DC output, adapting to diverse power supply requirements of industrial control systems.
3. Comprehensive Protection Functions: Equipped with overvoltage, undervoltage, overcurrent, and short-circuit protection, effectively safeguarding the power supply board and connected control components from electrical damage.
4. Seamless System Compatibility: Specifically designed for ABB industrial automation systems, fully compatible with UNITROL 5000 excitation systems, frequency converters, and other ABB control equipment, ensuring plug-and-play integration.
5. Industrial-Grade Durability: Constructed with high-quality flame-retardant PCB materials and rugged metal housing, resistant to dust, vibration, and temperature fluctuations, complying with international industrial safety standards and ensuring long-term stable operation in harsh industrial environments.
6. Real-Time Monitoring & Fault Diagnosis: Equipped with analog and digital input/output channels, supporting real-time monitoring of power supply parameters and fault alarm, facilitating timely fault diagnosis and maintenance.
7. Easy Installation & Maintenance: Compact modular design, clear terminal labeling, and standardized mounting holes, enabling quick installation and on-site replacement without disrupting the entire control system.
Output:
1.Power Output:
Dual-channel stable power output, each channel providing 24V DC rated voltage, rated current 5A, output voltage ripple ≤50mV, ensuring stable power supply for connected control modules, sensors, and other low-power devices;
each output channel is independently protected against overcurrent and short circuit.
2.Signal Output:
2 analog output channels (4–20mA) for transmitting real-time power supply status signals (such as output voltage, output current) to the main control system, enabling remote monitoring and fault diagnosis;
2 digital output channels for sending fault alarm signals (such as overcurrent, overvoltage, short circuit) to trigger corresponding protective actions.
3.Communication Output:
Compatible with ABB proprietary industrial communication protocols, facilitating coordinated operation with other ABB control modules and equipment, realizing integrated control and management of the entire power supply and control system.
