1. Core Hardware Interface Specifications
1. Ethernet Port
1. 10/100Mbps Auto-sensing RJ45, Modbus TCP/IP protocol
Supports TCP Client (Master) + TCP Server (Slave), up to 20 concurrent connections
Compatible with HMI, SCADA, PLC, and upper-level monitoring systems for simultaneous reading and writing by multiple ends
2. Four Independent Isolated Serial Ports (MBS4)
4 completely isolated serial ports, each port can be independently switched: RS232 / RS422 / RS485;
Each serial port can be set as Modbus Master (Master) or Modbus Slave (Slave)

Baud Rate: Up to 115.2 kbps
Protocol: Modbus RTU / Modbus ASCII
Up to 32 slave stations on a 485 bus, a total of 4 ports can connect up to 400 Modbus serial devices (with repeaters)
Electrical Isolation: High-voltage isolation between serial ports, power supply, and ground loop interference is eliminated
3. Power Supply and Mechanics
Power Supply: 10 – 36 VDC wide voltage range, nominal 24 VDC; typical power consumption 300 mA, maximum 610 mA
Installation: Standard 35mm DIN rail snap-in installation
SD Card Slot for Storage (optional SD card): Backup / Quick recovery of all configuration programs, one-click import of configuration upon device replacement
Panel LEDs: Power, Ethernet link, transmit/receive, status indicators for four serial ports
Environmental Parameters
Operating Temperature: -25°C ～ +70°C
