16 Channel Dry Contact over Ethernet Converter (with WEB and SNMP Management)

This industrial rail-type dry contact server is IP40 protection grade. It is a dry contact network server that can immediately enable dry contact devices to have networking capabilities. This product supports 16 channels of DI or DO, DI supports dry contact input mode, and DO supports dry contact output and pulse output. It can convert dry contact to 2*100M Ethernet ports to meet the needs of dual IP and dual MAC addresses/multi-network management or network backup, and it can be installed on 35mm rail or wall.

The dry contact server supports multiple network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, SNMP, Telnet, SSH and other protocols; it has complete management functions, supports access control, quick configuration, online upgrade, etc., supports Modbus TCP, and other working modes; support WEB access mode. In addition, the management and configuration tool based on the Windows platform is provided to realize the immediate networking of the dry contact devices through simple settings. The interface design of the network management system is friendly, and the operation is simple and convenient, which can bring you a good user experience.

The hardware adopts fanless, low power consumption, wide temperature and wide voltage design, it has passed strict tests in line with industry standards and can adapt to the industrial field environment with strict requirements for EMC.
