Modbus (RTU and/or TCP) compatible I/O-module UF040404 and UF040404E


These extension modules have 4 AI, 4 DI, and 4 DO channels. The main purpose of these modules is to make available even more I/O channels for the UFK040404 or UFK080808 controllers.

However, the I/O expansion modules are also compatible with any other master device that complies with the Modbus standard.

UF04040404E also includes an Ethernet port, which makes it usable (either with a controller or independently) as a ModbusTCP server, ModbusTCP/RTU gateway or ModbusRTU/TCP gateway.
