Part Identity and Sourcing Context
The Omron K3NX-VD2A is a digital process panel meter, classified under Measurement and Indicators within the Automation and Control Systems category. This is the part number for a panel-mount indicator used to display a process variable — typically a 4-20 mA or voltage signal from a transmitter — as an engineering unit reading on a local display.
A digital process meter like the K3NX-VD2A accepts an analog input from a field sensor — pressure, temperature, flow, level — and scales that signal to display the measured value in the operator's chosen units. The front-panel display gives a local readout, while the unit's output options (if equipped) can drive alarms or retransmit the signal to a PLC or DCS. Panel-mount meters are common in control-room panels, local operator stations, and skid-mounted equipment where a direct readout is needed without opening the HMI screen. The panel cutout and depth are not specified in this listing, so verify the existing panel opening against the K3NX series installation manual.
No pin-compatible alternative is listed, so the K3NX-VD2A is the direct drop-in for any existing panel cutout wired for this model.
