EMV 1200-40 is an easy-to-mount LCD digital panel meter. To install the meter, the user need only drill a single 7/32” (5.5mm) hole in the panel. The module is fitted to the panel by locating its threaded stud through the hole, fitting the washer and tightening the nut provided. The module's connecting wires pass through the hollow stud into the target application for connection. The module features a 4 to 40V measurement range with 200mV resolution and is powered from the signal it is measuring. Only valid readings are displayed; the module indicates "LO" at voltages below 4V and "HI" at voltages above 40V. A rubber seal is included, providing splash proof protection for the unit when fitted to the meter during installation.
