The Omron K3GN-NDC-FLK 24VDC is a panel-mount process meter from the K3GN series, built to display and monitor analog process signals — 4-20 mA current loops or ±10 VDC voltage inputs — on a dual-color LCD backlit display with five 7 mm characters per row. Two relay outputs let it trigger alarms, start a pump, or signal a PLC when a process variable crosses a setpoint — no separate comparator module needed. The serial communications output transmits readings upstream for data logging or SCADA integration.
It mounts into a rectangular panel cutout 45.00 mm x 22.20 mm — a common footprint for compact process indicators — and secures with screw terminals on the back.
