Technical data for the overall system
Voltage supply:
Rated voltage 24 V/DC
Tolerance - 15% / + 20%
Valve types 0460, 0461 - 10% / + 10%
Valve type 6524 (2x 3/2-way) - 15% / + 10%
Current carrying capacity:
Logic area 1 A
24 V area 2.5 A
Maximum current consumption:
I_module proportion of current in the logic area of the basic electronic modules
max. 75 mA
I_valve valve current before and after power reduction
Temperature:
Storage temperature - 20 to + 60 °C
NOTE The admissible ambient temperature is depent on the modules used. During assembly, the
crucial factor is the most critical module.
Valve type 6524, 6525, 6526, 6527 0 to + 55 °C
Valve type 0460, 0461 0 to + 50 °C
After the field bus nodes 1734-APB, 1734-ADN and 1734-PDN, 13 modules can be placed
in each case. After this, 13 further modules may be connected in each case by attaching
power supply units. The total number of modules must not exceed 63.
