2.4.1 Technical Description
PIN 1: Power Supply (terminal 30)
V
Batt
= + 10,5 V to + 32 V
The instrument is supplied with permanent power through this terminal. Current consumption varies depending on the instru-
ments operating mode (standby or active) and number of Slaves.
PIN 2: Ground (terminal 31)
Power ground of the instrument.
PIN 3, 4: CANbus Interface 1
High-Speed Full CANbus V2.0B compatible (10, 20, 50, 125, 250, 500 kbit/s, 1 Mbit/sec.).
12 V and 24 V system compatible.
Cable: shielded, twisted pair with a drain.
Cable Impedance: nom. 120 Ω.
Topology: linear Bus
Trunk Length: max. 40 meters
Drop Length: max. 1 meter
Termination: 2 resistors 120 Ω at each end of the bus.
