Overview

Technical Parameters

• Power Parameters: Supports a 24V DC working power supply, with a wide voltage fluctuation adaptation capability of ±15%, and can be stably connected to the common industrial DC power supply system to meet the needs of complex power supply environments.
• Protection Function Parameters:
• Overcurrent Protection: Covers instantaneous and time-delayed overcurrent functions for phase, neutral point, ground/sensitive ground, and is equipped with time-delayed overcurrent protection for negative sequence current. It has IEEE/ANSI, IEC A/B/C/long inverse time/short inverse time, GE IAC, I²t, definite time, rectifier curves, and four user-defined curves, adapting to the overcurrent characteristics of different power systems.
• Directional Elements: Phase, neutral point, ground, and sensitive ground currents are all equipped with directional functions. The neutral point/ground directional element can be programmed to operate based on zero-sequence voltage, ground sensitive current, or dual polarization conditions.
• Voltage Protection: Provides phase/auxiliary overvoltage, undervoltage, as well as neutral point and negative sequence overvoltage protection, comprehensively ensuring the voltage stability of the power system.
• Frequency Elements: Equipped with three independent frequency units, which can flexibly set underfrequency or overfrequency protection, commonly used in power system load rejection scenarios.
• Circuit Breaker Failure: Has two levels of current and two levels of time delay settings, including a tripping function without a current element and an internal arcing current detection element. The circuit breaker failure element is divided into three levels: "re-trip" or "monitoring", "high level", and "low level". Its function can be activated or blocked through digital input and communication.
• Automatic Reclosing: Applicable to three-phase tripping schemes and single circuit breaker applications, can perform 4 closing operations before locking, and each closing time can be independently set. The automatic reclosing output can be used to adjust the circuit protection settings between closings.

• I/O Interfaces: Can flexibly choose within the range of 16-32 digital inputs and 8-16 digital outputs. Digital inputs support customization and are equipped with independent debounce and vibration delay functions; some inputs support programmable "approximate analog", which can adapt to different voltage levels by setting thresholds.
• Network Performance: The Ethernet interface supports a transmission rate of 10/100Mbps and has an auto-negotiation function, which can adapt to the connection needs of different network devices and ensure stable data transmission.
• Environmental Adaptability: The operating temperature range is -10℃ to +60℃, and the storage temperature range is -40℃ to +85℃; the relative humidity is 5%-95% (non-condensing); the protection level reaches IP20, suitable for installation in control cabinets to resist dust and slight moisture, ensuring stable operation in industrial environments.
• Physical Specifications: The overall size is compact, facilitating installation and layout; specific dimensions can refer to the product manual; supports DIN rail mounting, effectively saving space in the control cabinet.
• Certification Standards: Strictly complies with standards such as CE and UL 508, and has passed industrial electromagnetic compatibility (EMC) testing, ensuring the stability and reliability of communication and functions in complex electromagnetic environments.
