32 Port Dry Contact Closure over Ethernet Converter (with WEB and SNMP Management)

This industrial DIN-rail dry contact to ethernet converter has an IP40 protection level and is a dry contact network server that provides immediate networking capability to dry contact devices. It supports 32 channels of digital input or output (DI/DO), with DI supporting dry contact input mode and DO supporting dry contact output and pulse output (wet contact) modes. It has two 100Mbps Ethernet ports, providing dual IP and dual MAC addresses for multiple network management or network backup needs. It can be mounted on a 35mm DIN rail or wall.

The dry contact server supports multiple network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, SNMP, Telnet, and SSH. It has comprehensive management functions, including access control, quick configuration, and online upgrades. It supports up to 4 TCP or UDP sessions and various working modes such as Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and more. It also supports WEB access. Additionally, the device comes with a Windows-based management configuration tool that allows dry contact devices to be connected to the network through simple settings. The network management system interface is user-friendly, easy to operate, and provides a good user experience.

The hardware design is fanless, low power consumption, wide temperature, and wide voltage. It has undergone strict testing that meets industry standards to adapt to industrial environments that require strict EMC requirements.
