UNITRONIC® BUS CAN UL/CSA

Standardised internationally in ISO 11898. Maximum bit rate: 1 Mbit/s for 40m segment length. Larger conductor crosssection necessary with increasing length. Also in case of power supply over a second pair due to increasing attenuation. See Table below (reference values from ISO 11898).
