Fig. 10: Connection of the low-side digital outputs (PWML, BL), example CR0709
The controller can be connected to the following loads:
•
resistive loads
•
capacitive loads (adapt diagnostic settings to the load, see programming manual)
•
inductive loads
The connected load must not exceed the maximum permissible values of the respective output (
Ò
Technical data).
u
Supply low-side outputs (B
L
) via a high-side output (B
H
) of the same output group.
Deviating connections are not permitted.
6.12 Mixed operation (12 V / 24 V)
Mixed operation is not permissible when supplied by PELV.
Mixed operation only permissible when supplied by on-board system.
