*1. A control power supply capacity greater than the rated capacity is required when the Digital Panel Meter is turned ON.
Do not forget to take this into consideration when using several Digital Panel Meters. When power is supplied, all
indicators will light and outputs will be OFF. When using startup compensation time operation, the display will read
“00000” and all outputs will be OFF.
*2. Enabled only when using DC voltage/current input. (Min.time for control signal input: 80 ms)

K3GN
Mounting Recommended Panel Thickness 1 to 5 mm. Mount the product horizontally.
- For installation, insert the K3GN panel into the rectangular hole, insert the adaptor from the rear, and push it in to reduce the gap between the panel surface and the adaptor. Secure the Unit with the screws. For water-proof installation, insert the rubber gasket onto the body of the K3GN.
- If multiple mounted Units are used, make sure the ambient temperature for the K3GN does not exceed the specified temperature.
Features | Digital Panel Indicator – K3GN
