Does X80 discrete IO modules have short circuit protection in-built.

How can we help you today?

Built-in protection is available for X80 discrete IO modules. However use fast blow fuse on output field terminal of appropriate rating. Below are the built in protections available in X80 DO modules:

against over voltage = Yes, by Transil diode
against inversions = Yes, by inverted diode
against short-circuits and overloads = Yes, by current limiter and electric circuit-breaker 1.5 In < Id < 2 In
