The Cgate3208 is a din-rail industrial Modbus gateway with 8*serial ports. It supports serial port conversion to UDP, TCP, Modbus, HTTPD, WebSocket, MQTT and other protocols, and can realize communication between Modbus RTU/ASCII and Modbus TCP protocols. This product provides 2*100M copper ports and 8*RS232 or RS485 serial ports to choose from. It supports DC12~48V dual power supply redundant input. The power supply connection has no polarity.
The product supports WEB configuration of various network management functions, such as serial port/network working mode, serial port forwarding, network card mode, DNS, access control, IP/MAC filtering, log management, email alarms, SNMP alarms, serial port restart, system management, etc; it supports Modbus RTU Master/Slave, Modbus ASCII Master/Slave, UDP, TCP Client/Server, UDP Multicast, RealCOM_MCP/CCP/MW, Pair Connection Master/Slave, HTTPD Client, WebSocket Client, MQTT and other conversion modes to realize serial port to Ethernet network or Modbus TCP protocol. The Modbus gateway supports one-click restart or factory reset. The hardware adopts high-standard industrial protection design, with industrial-grade components and high-strength aluminum alloy casing, which is sturdy and durable; it is featured with low power consumption, wide temperature and wide voltage design, fanless casing for heat dissipation, and supports -40℃~+85℃ operating temperature, passed strict safety regulations and EMC tests to meet the application needs of harsh industrial environments. The Mgate3208 series can be widely used in industrial automation, integrated energy, smart cities, smart transportation, smart mines, smart factories and other fields.
