Parameter
Voltage
Typical power consumption
Signal level (including ripple)
Pins 7, 8, 10 and 11 are "rapid inputs"
Signal propagation delays for "rapid inputs"
Galvanic isolation
Voltage
Maximum load current per output
Maximum load current per connector
Note
An open input is interpreted as "low".
Only "rapid inputs" can be used as inputs for BEROs.
Terminals MEXT1 ... MEXT6 must be connected for the digital inputs/outputs to work. This
can be done as follows:
• Connect the ground reference of the digital inputs.
• A bridge to terminal M on plug connection X1.

Technical data for the digital inputs/outputs of X122/X132/X142
DANGER
Notice: This removes the galvanic isolation for these digital inputs.
