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 lowcurrent consumption.This product is designed sono soldering is required. Connection is
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. Itis secured withthe nut provided. Protection fromthe front to IP67
/ NEMA 4Xstandards is achievedby placing the rubber seal betweenthe module andpanel during assembly.

SAFETY

To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed
60Vdc. The user must ensurethat the incorporation of the panelmeter into the user’s equipment conforms to the
relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and
Laboratory Use).
