This device is an industrial media converter with one 10 Mbit/s RJ-45 ETHERNET port (10BASE-T) and one Single Pair Ethernet port (10BASE-T1L). The media converter enables ETHERNET communication at a bandwidth of 10 Mbit/s using shielded twisted-pair cabling over a maximum transmission distance of 1,000 m (approx. 3,280 ft). The automatic transmission rate detection (auto-negotiation) of the connected ETHERNET device enables simple plug-and-play operation. Connecting the SPE cable to the female connector with lever actuation is straightforward and time-efficient. Using Single Pair Ethernet significantly reduces the cost of integrating an Ethernet connection over long transmission distances. In particular, reusing existing cabling can significantly reduce the cost of connecting decentralized Ethernet-capable sensors to an automation system. Another application involves networking remote Ethernet devices using two SPE media converters over a maximum distance of 1,000 m (approx. 3,280 ft). This application makes it possible to substitute DSL modems or fiber optic connections. Its compact design with a DIN-rail adapter makes installation in control cabinets easier and provides high heat, vibration and shock resistance. The device operates on 24 VDC, the standard supply voltage used in control cabinets.
