Chapter 4. Power Distribution

The Güralp 40TDE is powered using the DATA connector. Incoming voltage and current are monitored. From here, power is routed through various switches and monitors (indicated by circled 'A's) to various parts of the instrument and to outlets on the GPS and ETHERNET connectors, as shown in the diagram below.

Monitored voltages and currents (and calculated wattages) can be displayed in real-time, using the Digital I/O page of the web interface, and stored for future use via the Environment Logging system, which also allows downloading or graphical display of historical values.
