EM32-1B-LED

Round Hole Mounting LED Voltmeter

PRODUCT DESCRIPTION

The EM32-1B-LED isa3½digitLEDvoltmeterwhichis designed to be panel mounted in most low and medium
volume applications. The meter features 8mmdigitheight,3decimalpoints,auto-polarity, auto-zero, 200mVfull
scale reading and a low current consumption. This product is designedsonosolderingisrequired.Connectionis
via screw terminals, and options are selected via jumper links. The module features a round metal bezel,
requiring a 32.5mm (1.28") diametercut-out. It is securedwiththenutprovided.Protection from thefront to IP 67
/ NEMA 4Xstandards is achieved by placingthe rubber seal between the moduleand panel during assembly.

SAFETY

To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pinsmust notexceed
60Vdc. The user must ensure thatthe incorporationof the panel meter into the user’s equipmentconforms tothe
relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and
Laboratory Use).
