Rail Mount Serial Server 2 Ch RS485 To RJ45 Isolated Ethernet Module

Industrial Rail-Mount Serial Server, Isolated 2-ch RS485 to RJ45 Ethernet Module, is a versatile data acquisition and IoT gateway tailored for industrial settings. It supports RS232/485/422 protocols and integrates several functionalities into one unit, serving as a serial server, Modbus gateway, MQTT gateway, and RS485 to JSON converter.

Equipped with 2-ch RS485 and Ethernet ports featuring Power over Ethernet (PoE) capability, it facilitates convenient power input via a DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and screw terminals. Its compact case design, complemented by rail-mount support, ensures easy installation. It is a cost-effective solution for various applications, such as data acquisition and IoT gateway deployment within industrial environments.
