4-port RS-485/422 Device Servers with Digital I/Os and Analog

SE5124/SE5224 Series are serial device servers that can make serial device be equipped with networking capability instantly and centrally manage the scattered serial devices and hosts via network. This product supports 4 RS-485/422 combo serial ports to 2 100M Ethernet copper ports which supports electromagnetic isolation. It adopts DIN-Rail or wall mounting to meet the requirements of different application scenes.

SE5124/SE5224 Series support multiple network protocols, such as TCP, UDP, TELNET, ARP, ICMP, HTTP, DNS and DHCP protocol. It also possesses complete management functions, including Access Control, Rapid Configuration, Online Upgrading and so on. Each serial port supports 4 TCP or UDP session connections, and it also supports TCP Server, TCP Client, UDP Server and UDP Client operating modes and Telnet , Web access modes. 
SE5124/SE5224 provide 2 10/100Base-T (x) RJ45 ports and 4-channel RS-485 serial ports. It has two separate LAN ports that can be connected to separate LAN networks. Dual-LAN redundancy involves setting up two separate physical networks to connect the PC host with the SE5124/SE5224 (the PC host also requires two LAN cards). If one connection fails, the PC host can still communicate with your serial devices over the alternative LAN connection.

Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in PLC control and management, Building Automation System, Health Care Automation System, measuring instrument and environmental forces monitoring system.

SE5124/SE5224 Series have built-in digital I/Os, provide maximum flexibility when you need to integrate serial equipment in the field with an Ethernet network. The combination of digital I/Os makes the device servers well-suited for a variety of industrial data acquisition applications. The DI/Os on the device can be controlled over TCP/IP using the Modbus TCP protocol and can be configured from a web browser.
SE5124/SE5224 Series products realize the signal acquisition between sensor and host, to measure analog signals. The products can be applied to RS-232/485 bus industrial automation control system, 4-20mA signal measurement, monitoring and control small-signal measurement and signal isolation and long-term industrial transmission and so on. Products include power supply isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication.
