Simpson Electric M23500340 Digital Panel Meter

The Simpson Electric M23500340 Mini-Max LCD digital panel meter is a 3-1/2 digit instrument in Simpson’s M235 series, designed to display voltage with a compact, panel-mount form factor for electrical control panels, test benches, instrument enclosures, and other sheltered electrical installations. In typical configurations, the M235 family is powered from AC 85–250 VAC, and the 3-1/2 digit LCD readout provides a clear, easily readable voltage indication; the exact model M23500340 is identified by order number M23500340 and sits within the Mini-Max lineup focused on compact size and reliability. The M235 meters can be powered by AC (85–250 VAC @ 40–440 Hz) or DC (9–32 VDC), depending on the installed variant, and offer an optional display backlight (0 = none, 1 = red LED backlight, 2 = red negative-image) to boost legibility in tight panels or low-light environments. A distinctive feature for panel density is Simpson’s mounting bracket that allows stacking multiple meters in a single panel cutout, enabling compact, multi-channel voltage monitoring in one enclosure and simplifying wiring and layout in control cabinets.
