MB5904D Series

4-Port Industrial Secure Modbus TCP/RTU/ASCII Gateway with Optional 3kV isolation, DIN-rail mount, dual power input, wide-temperature

Overview

MB5904D Series Diverse Hardware Infrastructure Modbus Gateway supports the four most commonly used communication standards, RS-232/485/422, and Ethernet. The ease-of- use configuration utility provided with Modbus Gateway can quickly select the hardware interface , and easily switch to the existing communication infrastructure. Industrial EMC protection and wide temperature operation capability make MB5904D ready for every mission. And if cabling is an issue, the PoE-powered version can allow MB5904D to be powered through PoE. Embedded Security and advanced features Relax. MB5904D Modbus Gateway supports OpenVPN and IPsec VPN encryption, allowing you to safely use the device over the internet without worrying about malicious attacks, data sniffing or unintentional remote control of your Modbus slaves. On your LAN, RSTP protocol will provide an additional layer of security in case of link losses.
