FOR DIN-rail Serial device server 5443D — 4 port Isolating RS485 to Ethernet TCPIP Converter Modbus RTU TCP Gateway

The FOR 5443D is a DIN-rail mount serial device server that converts four isolating RS485 ports into Ethernet TCPIP links. It operates as a Modbus RTU TCP Gateway, enabling Modbus RTU serial devices to be accessed over TCPIP networks. Built for industrial environments, this 4 port converter provides reliable serial-to-Ethernet connectivity for PLCs, HMIs, SCADA systems and other RS485 equipment. Compact and easy to install on a DIN-rail, the 5443D simplifies integration of legacy serial devices into modern Ethernet infrastructures.
