With the output channels CH0, CH1 and CH2, up to 3 load
groups can be switched in a safety-oriented manner inde-
pendently of each other.
From the perspective of the output module CPX-FVDA-P2, the
output channels (CH0 ... CH2) are channel pairs, since in each
case two paths are always switched commonly and simultan-
eously but independently of each other. One channel forms
the positive (P) and one the negative (M) path for a potential-
free load voltage supply.
All P- and M-switches of the module’s output channels are
each controlled by different processors, which permanently
monitor each other (safety concept).
The output channels 1 and 2 (CH1 and CH2) are suitable, for
example, for load voltage supply of components that must be
switched off safely, as needed, and that fulfil the correspond-
ing requirements (
section 1.4 and technical data in the
appendix).
Examples:
–
Soft-start/quick exhaust valves for external components
or internal valve terminal pneumatics.
–
Valve groups within the CPX terminal, which are separ-
ately supplied through electrical supply plates.
–
Output signal groups, which are supplied through an ad-
ditional electrical power supply.
These can be arranged in both their own and a separate
valve terminal.
–
Integrated voltage supply of an additional valve terminal.
The operating voltage for electronics and sensors U
EL/SEN
is supplied from the unswitched auxiliary voltage supply
and the load voltage U
VAL
/U
OUT
from an output chan-
nel (CH1 or CH2). If requested (in the functioning case),
the load of the additional valve terminal is switched off
without influencing the communication and input func-
tion.
