Surge Current
|
The surge current of the B838 is 2.5 A for 0.5 ms, and should not be exceeded. If a short circuit (momentary or sustained) ex-ists, the FET on the output may fail prior to the group fuse blowing. Modicon recommends one of the following options to protect the outputs:1) Add external fuses to each output (1 - 1.5 A fast blow),2) Add external current limiting resistors to protect the output FET
