10 RC10-10 Series 31 | BODAS Controller
Connection diagram
Footnotes for the connection diagram
1) Short, low-resistance connection from a case screw to the vehicle
ground.
2) Own ground connection to battery (chassis possible).
3) Loads connected to low side outputs must be powered from high
side outputs of the same controller. Stand-alone operation of low
side outputs is not permissible.
Deviations from that rule require additional measures. Please con-
tact Bosch Rexroth.
Combinations between high side and low side outputs different
from the ones shown are possible. These are examples only. For
more information see safout() function in the API manual.
4) CAN bus: 120 Ω termination resistor and twisted line necessary.
5) Constant voltage sources can be used as sensor supply or switch-
ing voltage for switches/push-buttons.
6) Can be adjusted to the actual current consumption of the consum-
ers and must be adjusted to the permissible loading of the lines
and pins.
7) If deactivated during operation, data will not be saved in the non-
volatile memory and there will be no after run.
8) First deactivation channel: deactivation with level < 4 V (open /
cable break); activation with level > 7 V (switch to terminal 30 or
30_1). When deactivated the respective main switch VP_x is off.
The main switches can be deactivated together (as shown) or sep-
arately.
9) Second deactivation channel: deactivation with level > 3 V (open /
cable break); activation with level < 0.4 V (switch to ground). The
second deactivation channel shuts of output stage control via the
processor’s emergency stop function.
For more information on deactivation channels please see the re-
spective programming manual and safety-relevant project planning
instructions.
10) Terminal 31 (PGND) and sensor grounds (SGND_x) are joined at a
star point in the controller and are connected to the housing.
SGND_1 shall be used for the ground connection of analog sensors
and SGND_2 shall be used for the ground connection of digital sen-
sors.
11) The total current out of OUT_1 and OUT_2 must not exceed 6 A.
The total current out of OUT_3 and OUT_4 must not exceed 6 A.
The designations (A), (B), (C) indicate the respective ADC channel
used for this input or current feedback.
