Vlinx MESR321 Series - Isolated Industrial Modbus Gateways

Vlinx™ MESR321 series Modbus Gateways connect Modbus devices to Ethernet networks and let you monitor and control your Modbus devices from anywhere on your Ethernet LAN or WAN. Supporting up to 16 masters and 32 slaves, the gateways feature auto-detecting SP 10/100 copper and/or fiber optic options that include Multi-mode LC and Single-mode LC.

The data ports are isolated from one another and also from the power supply.

The easy to use Vlinx software is compatible with Windows 2003 Server, XP, Vista, Win 7 and Windows Server 2008. It features Modbus messaging priority control and allows management through multiple TCP/IP client sessions. Serial data rates of up to 230 kbps ensure maximum network flexibility.

Featuring a slim IP30 DIN rail mountable case, MESR321 series gateways are built for use in industrial environments. They can be powered via a barrel connector or a terminal block. (An external power supply is required; sold separately.) The MESR321 has an additional Ethernet port which functions much like an Ethernet Switch, allowing pass-through connectivity for other Ethernet devices. This port can also be used to “daisy chain” multiple gateways.
