I. Input Signal Types1. Electrical Quantity Input (Measurement and Monitoring)

Analog Input (AI)

Supports current-type input: such as 4–20mA (standard industrial signal), used for collecting parameters like current and power, compatible with current transformers (CT) or transmitters.
Supports voltage-type input: such as 0–10V, 0–5V, used for monitoring signals like voltage and frequency, which can be connected to voltage transformers (VT) or directly sampled.
Measurement accuracy: Usually within ±0.5% FS (full scale), supporting synchronous collection of three-phase electrical parameters (current, voltage, power factor, etc.).

Digital Input (DI)

Number of input channels: Typically configured as 8–16 channels, supporting dry contacts (such as switch positions, relay states) or wet contacts (DC 24V signals).
Electrical characteristics: Compatible with DC 24V/110V/220V, with optoelectronic isolation, and anti-interference capability conforming to IEC 61000 standards.
Function: Used to receive external equipment statuses (such as circuit breaker opening/closing positions, alarm signals), triggering logic control or event recording.

2. Communication Input (Data Interaction)

Serial Communication Interface

Standard RS485/RS232, supporting protocols such as Modbus RTU and Profibus DP, used to connect sensors, instruments, or upper computers.

Ethernet Interface (Optional)

Supports protocols such as IEC 61850, Modbus TCP, and EtherNet/IP, enabling data interaction with SCADA systems, PLCs, or cloud platforms.

II. Output Signal Types1. Control Signal Output

Digital Output (DO)

Number of channels: Commonly 4–8 channels, supporting relay output (dry contacts, such as AC 250V/5A, DC 30V/5A) or transistor output (DC 24V/1A).
Function: Controls circuit breaker opening/closing, signal relays, alarm devices, etc., with hardware interlock and overload protection.

Analog Output (AO)

Output signals: 4–20mA, 0–10V, used to transmit measurement data to other devices (such as recorders, human-machine interfaces), with accuracy of ±0.5% FS.

2. Communication Output (Data Transmission)

Compatible with input communication interfaces, supporting the output of internal data (such as measured values, fault statuses) to external systems through Modbus, Profibus, or Ethernet protocols for remote monitoring.

III. Special Function Interfaces (Possible Configurations)

Pulse Input/Output

Used for metering electrical energy pulses (such as energy meter pulse input) or outputting control pulses (such as motor speed regulation), with a frequency range typically 0–10kHz.

Synchronous Clock Interface

Supports IRIG-B and SNTP clock synchronization to ensure time consistency among multiple devices, suitable for fault recording and sequence of events (SOE) recording.
