The EM32-1B-LED is a 3 ½ digit LED voltmeter which is designed to be panel mounted in most low and medium volume applications. The meter features 8mm (0.31") digit height, 3 decimal points, auto-polarity, auto-zero, 200mV full scale reading and a low current consumption. This product 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 (1.28") diameter cut-out. It is secured with the nut provided. Protection from the front to IP 67 / NEMA4X standards is achieved by placing the rubber seal between the module and panel during assembly.
