Seeking help with a digital display instrument
Thread Content
I’m looking for a digital display device that operates on 220V power, with one analog input channel. The interface should allow setting a specific value, and the device should provide a percentage alarm based on the comparison between the analog value and the set value; this percentage can be adjusted on the interface. It would be ideal if the alarm function included a 24V output. Thank you everyone

A light column display will do
