What it is and what it measures
The Omron K3HB-XVD-A1 24VAC/VDC is a panel-mount process meter from the K3HB-X series, built to display DC voltage over a ±199.99 VDC range on a five-digit dual-color LCD with backlight. It accepts a 24 VAC/VDC supply and terminates via screw terminals, making it a straightforward drop-in for existing panel cutouts at 92.00 mm x 45.00 mm. The IP66-rated front means the display and keypad survive washdown environments — think food processing or outdoor cabinets where hose-down cleaning is routine.
Key features for the panel builder
Dual-color characters (red/green) let you flag an out-of-range condition at a glance without staring at the numeric value — useful for a quick visual scan on a multi-meter panel. An event input and an excitation supply are built in, so you can trigger a hold or reset from a remote contact and power a 2-wire transmitter directly, saving an external loop supply. Rated for -10°C to 55°C ambient, so it handles a warm enclosure near a drive cabinet without derating, but keep it away from direct steam or oven exhaust.
Lifecycle and sourcing
Because it's an active, standard-series meter, sourcing is straightforward — quoted to order against an RFQ, no last-time-buy or broker scavenger hunt needed.
