Universal Input Digital Panel Meter(4-digits red display, AC input) – N24 Z type

Description PRODUCT DESCRIPTION Indicators of N24 series are destined for measurement of d.c. voltage or d.c. current, temperature from Pt100 sensors and J, K thermocouples, a.c. voltage and a.c. current. Thank to competitive price they are ideal solution for low-budget applications. Features: 4-digit LED display, digits of 20 mm high, Possible configuration of parameters through the PD14 programmer and the free delivered LPConfig program, precision of displayed results (decimal point), measurement averaging time, recounting of indications (individual characteristic), automatic or manual compensation: temperature of cold junction for measurements with thermocouples or wire resistance for Pt100 sensors (N24T), Supply: 85…253 V a.c./d.c. or 20…24 V a.c./d.c., 110 V a.c., 230 V a.c.
