PDS320
Dual Self Supply Protection Relay
The PDS320 protection relay is designed for modern electrical power distribution systems, combining dual self-supply and external power features to ensure continuous operation. It delivers fast fault detection and isolation, while offering comprehensive, reliable, and user-friendly protection for critical energy infrastructures.
Key Features
- Controllable and monitorable via integrated HMI: Allows local monitoring and configuration through the built-in human-machine interface, eliminating the need for external tools.
- Expanded position functions for enhanced system control: Supports advanced operating scenarios by enabling flexible logic and control configurations.
- Increased number of I/O ports for broader integration: Offers additional digital and analog inputs/outputs to accommodate a wide range of monitoring and control needs.
- Supports IEC 60870-5-103 and Modbus RTU protocols via RS485: Ensures seamless integration into existing SCADA and automation systems through standardized communication protocols.
- Multiple supply options for increased reliability: Operates via self-supply or external auxiliary power (20-130V) and Externally powered by battery for configuration access and event log retention during power outages.
