This supply module powers all intrinsically safe 750 Series Ex i Modules. It also monitors the power supply to the downstream Ex i segment and separates the intrinsically safe from the non-intrinsically safe section of the WAGO I/O System 750. The input and output sides are electrically isolated from each other.
The maximum current provided by the supply module is 1.0 A. When configuring the Ex i segment, the total current must not be exceeded.
In the event of a short circuit or overload, electronic monitoring automatically switches off the output voltage. After eliminating the fault, the output voltage is reactivated within approximately ten seconds.
If, due to load conditions, more than one supply module is required per station, four distance modules (750‐616) must be placed between the intrinsically safe sections.Indicators:
