In addition, take into account the PROFIBUS DP communication time and the application cycle time.
A polarity reversal does not cause a high signal level nor does it destroy the outputs.
General electric features:
S Galvanic isolation through opto-couplers
S Current limited to max. 0.25 A
S Protection from:
– short-circuit
– overtemperature
– loss of grounding
S automatic shutdown in case of undervoltage
