Lumel-N30U
Programmable digital meter of temperature, resistance and standard signals

The N30U meter is destined for the measurement of temperature, resistance and standard signals Input: temperature: resistance thermometers: Pt100, Pt500, Pt1000 thermocouples: J, K, N, E, R, S resistance: 400 ohm, 4000 ohm current: ± 20 mA voltage: 0…10 V, -10…60 mV Output: relay (4), analog (1), digital RS-485/MODBUS (1), Three-colour display - red, green and orange, programmable in three intervals of the measured value – facilitates the observation of measured value changes. digit height: 14 mm highlighted measuring unit Four alarm outputs with signaling on LED diodes operating in six different modes. Conversion of any measured value into an analog signal: 0/4…20 mA or 0…10 V. Storage of minimal and maximal values for all measured quantities, Mathematical functions - avalaible from 2.04 version Meter programming from the keyboard or through the RS-485 interface by means of the free eCon software One can reprogram following parameters: display colour, individually in three intervals, thresholds of displayed overflows, display precision of the result (decimal point), unit highlighting, measurement averaging time, recount of indications (individual characteristic), parameters of alarm outputs. Supply: 85…253 V a.c./d.c. or 20…40 V a.c./d.c. Casing protection grade : IP65 Overall dimensions: 96 x 48 x 64 mm  Check part numbers/executions available in the stock
