MDW-45 DIN Rail RS-485 Converter
MDW-45 is designed to meet industrial demands for reliability and functionality in environments with high levels of interference. MDW-45 is an interface converter between RS-232 and RS-485/422. The device can be used in multidrop and point-to-point applications to communicate on 2-wire or 4-wire connections up to 1200 metres (4000 ft) and with 32 connected devices in bus oriented applications. In 2-wire half-duplex communication (RS-485) MDW-45 can automatically control the data flow depending from which side the data is sent. Greater transmission ranges or additional connected devices on the bus can are possible with one or more repeaters. MDW-45 is designed for mounting on 35 mm DIN-rails.
