The feedback energy for a digital output module can be calculated as follows:
P =
Σ
all channels
1/2 n
i
* L
i
* I
i
²
P
Feedback energy of the module
N
i
Switching cycles of Channel i in 1/seconds
E
i
Feedback energy when shutting off Channel i during a shutdown
procedure
I
i
Current through the load connected to Channel i
L
i
Inductance of the load connected to Channel i
Once the maximum permissible feedback energy E
max
is reached, the module shuts down.
Maximum Feedback Energy Varies with Ambient Temperature
