The K3GN-NDC-L1 24VDC: The Omron K3GN-NDC- 24VDC is a panel-mount process meter from the K3GN series. It accepts a 4~20mA current loop or a ±10VDC voltage signal as its measuring input. The 5-digit LCD shows the reading in dual-color characters with a backlight — useful for a quick red/green status at a glance on a panel. Display character height is 0.275" (7.00mm), readable from a few feet away in a control room.
Outputs and control logic
Two relay outputs plus a re-transmission analog output come standard. That means the meter can both trigger an alarm or a shutdown at a setpoint (relay) and send the scaled process value to a PLC or DCS analog input card simultaneously. Screw terminals on the back make field wiring straightforward. The IP66-rated front panel holds up against washdown spray and dust ingress — a good fit for food-and-beverage or pharmaceutical panels where a hose-down is part of the sanitation cycle. The rear of the unit is not sealed, so the enclosure cutout gasket is what keeps the panel interior dry.
Panel fit and power
Panel cutout is rectangular at 45.00mm x 22.20mm — a standard 1/32 DIN-ish footprint, though verify against your existing punch if replacing a different brand. Supply is 24VDC only — no universal AC/DC input on this variant. Pulls the listed power from a 24V control transformer or a DIN-rail power supply; plan for a dedicated breaker or fuse on that circuit.
