128-Channel Dry Contact over Ethernet Converter (with WEB and SNMP network management)

The 19 inches rack type dry contact to ethernet converter is a dry contact network server that enables dry contact devices to immediately have networking capabilities. The product supports 128-channel DI or DO, DI supports dry contact input mode, DO supports dry contact output and pulse output mode. There are 2 100 Mbit/S Ethernet ports, one of which is a 100 Mbit/s Ethernet Comb port (one 100 Mbit/S electrical port or one 100 Mbit/s optical port). The ports meet the requirements for dual IP and MAC addresses, multiple networks, or network backup.

The dry contact server supports multiple network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, SNMP, Telnet, and SSH. With perfect management functions, support access control, quick configuration, online upgrade, etc. It supports multiple TCP session connections, supports Modbus TCP Server, and other working modes; It Supports WEB access. It has a friendly interface design of the network management system, which is simple and convenient for operation, and can bring you a good user experience.

The hardware adopts fanless, low power consumption, wide temperature and wide pressure design, and can adapt to the harsh requirements of EMC industrial field environment through strict testing in line with industry standards.
