Power supply: DC 24 V. Diagnosis: Intrinsically safe. The power supply module is designed to supply all intrinsically safe Ex i modules of the 750 series. It monitors the power supply of the downstream Ex i segment and separates the intrinsically safe part from the non-intrinsically safe part of the WAGO I/O System 750/753. The input and output sides are galvanically isolated. The maximum current provided by the power supply module is 1.0 A. When assembling the Ex i segment, it is important to ensure that this total current is not exceeded. In the event of a short circuit or overload, the output voltage is automatically switched off by electronic monitoring. After the fault is cleared, the output voltage is reactivated within approximately 10 seconds. Note: If more than one power supply module per station is required due to load conditions, four distance modules (750-616) must ensure the distance between the intrinsically safe segments. Indicators: Green LED (input voltage). Green/red LED (output voltage present/absent).
