About the Allen-Bradley 1783-NATR

The 1783-NATR is a configurable NAT router. Its DC supply input is 20.4…27.6V DC, limited voltage, at 150 mA, and it consumes up to 3 W. It works from -25…+70 °C in an open-style housing, and is rated for 5 g vibration at 10…500 Hz and 30 g operating shock.

What is the 1783-NATR used for?

It translates network addresses between two Ethernet networks, such as a machine network and the plant network. Insulation between the Ethernet ports and the power ports is functional. Emissions meet IEC 61000-6-4, with ESD, EFT/B, surge and conducted RF immunity ratings.
