MB5901 Series

1-Port Industrial Secure Modbus TCP/RTU/ASCII Gateway, DIN-rail mount, wide-temperature

Overview

Review the shared capabilities of the family, then select a model to see the characteristics that distinguish that ordering option.

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 MB5901 ready for every mission. And if cabling is an issue, the PoE-powered version can allow MB5901 to be powered through PoE. Embedded Security and advanced features Relax. MB5901 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.
Industrial EMC protection, wide temperature operation, -40°C~85°C
2-port 10/100Mbps Fast Ethernet, 1-port USB 2.0 high speed OTG
Bi-Directional Modbus TCP/RTU/ASCII conversion from Serial to Ethernet and Vice-versa
Advanced features include embedded IEEE802.1D-2004 RSTP Redundan- cy, SNMP v1/v2c/v3, Virtual ID remapping, VirtualCOM mode, exception handling and many others
IPsec or OpenVPN with high throughput, data-rate up to 37.9Mbps*
Rugged metal case with wall or DIN-Rail mount
