Powered by PV module

This supply concept enables a self-sustaining operation of the myDatalogEASY IoT ATEX . I.e. no energy source has to be available at the installation site. When installing the measuring device, it is important to note that all metallic mounting fixtures have to be grounded in a suitable manner and that the earthing connection of the myDatalogEASY IoT ATEX has to be connected to the ground potential (see Connection of the sensors and power supply).

The following components are required to implement the supply concept:

PV module 30W ATEX (301208)
PSU413D+ AP (300524)

Schematic diagram: supply via PV module

The myDatalogEASY IoT ATEX and the "PV module 30W ATEX " may only be operated in areas with a zone 2 explosive atmosphere. The sensors however may be operated in areas with a zone 0, zone 1 or zone 2 explosive atmosphere, provided they are approved for the relevant zone. As each of the two universal inputs has its own independent zener barrier, the senors with mA interface may also be operated in different zones.
