Universal Input Digital Panel Meter, N21

Description PRODUCT DESCRIPTION N21 is an ideal soluttion for visualisation of industrial processes. Universal input, universal supply and modern OLED display allow to apply meter in many applications. Features: Universal measuring input (for standard signals and cooperation with temperature sensors). Relay alarm output. Universal supply voltage from 24 V up to 230 V a.c./d.c. Supply of object transducers 24 V d.c. OLED display. Meter configuration through miniUSB connector with free eCon software. Programmable parameters in eCon software: selection of measured value, rescaling of indications (individual characteristic), accuracy of measured value (decimal point), alarm output mode, measurement averaging time, defining your own unit, language selection. Protection grade: IP65 External dimensions: 48 x 96 x 64mm.
