Industrial communication converter | 8 ports | from RS232/RS485 to Ethernet TCP/IP Modbus | 9-24VDC
Code: ES-ZLAN-5843AIndustrial 8-port converter for RS232/RS485 data transmission over an Ethernet TCP/IP network. It can convert serial communication into the TCP/IP protocol and supports Modbus gateway functionality, allowing connection of Modbus RTU devices to a Modbus TCP network.
The device features two 10/100M Ethernet ports, ensuring better connection stability and expandability. It supports the "multi-host" mode, allowing simultaneous data reading from multiple Modbus devices. The ability to expand up to 64 ports via Ethernet connection makes it a versatile and flexible interface for industrial systems.
