PM 148 DO 4
Restrictions imposed by power input
The maximum system configuration is limited amongst other things by the power
input of the load of the digital output modules in the configuration (see Section 2.7).
Limits for current consumption by load without use of power modules:
Limits for one ET 200X
Raising the limit
If the power input from the load exceeds the above limits, use power modules that
correspond to the load power consumption of your configuration. A power module
provides 10 A of load current for the downline digital-output modules.
