Outputs
The overload-safe outputs are equipped with protective diodes to protect the internal
circuitry. In the case of inductive loads (e.g. relay) each output should be additionally wired
with a protective diode mounted near the load in order to avoid EMC problems.
Max. 1 A current each output
Up to 3 A for all outputs
