The PCE-N20U is a voltage indicator used for signal processing. Designed for quick and easy system integration, the digital voltage indicator features a large 5-digit LED display with tricolor coding dependent on the measured values. The voltage indicator also can output signals via two open collector outputs when a threshold value is exceeded.
The two open collector outputs allow for the usage of external alarm systems in combination with the voltage indicator. The threshold values and other settings can be adjusted using the free software LPCon and the PCE-PD 14 programming adaptor (sold separately - see accessories for details). An integrated power supply system of 24 V allows for the direct connection of sensors and transducers to the voltage indicator. In addition, the face of the voltage indicator has an IP65 ingress protection rating against dust and water.
