The EM32-1B-LED is a 3.5-digit LED Voltmeter which is designed to be panel mounted in most low and medium volume applications. It is designed so no 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 diameter cut-out. It is secured with the nut provided. Protection from the front to IP67/NEMA 4X standards is achieved by placing the rubber seal between the module and panel during assembly.
