Loop powered display for the EVOMINI series temperature transmitters
4 digit display designed to be connected to the evomini series loop powered temperature transmitters; it requires no auxiliary power and is supplied directly from the measured current. The measured values are scalable and the programmation is done by the 3 integrated buttons key. The display has a compact, standardized
design and it fits into a standard 22.5mm borehole for signal lamps.
