LUMEL N20 Digital Indicator, 3-colour 5 digits LED display

The N20 meter is a digital programmable panel instrument destined for measurements of d.c. voltages, d.c. currents or temperature. The readout display is a LED display which enables the exposition of results in red, green or orange colour.

• Measurement of voltage or d.c. current and temperature (Pt100, J, K):
• Voltage:
• -11...-10...60...66 mV
• -1...0...10...11 V
• -11...10...10...11 V
• Current:
• -1...0...20...22 mA
• 3,6...4...20...22 mA
• -22...-20...20...22 mA
• Pt 100: - 50...400°C
• Type J T/C: - 50...1200°C
• Type K T/C: - 50...1370°C
• Three-colour LED display (5 digits, 14 mm high).
• 2 alarm outputs of OC type.
• Galvanic separation between the supply, measuring inputs and the programmer input.
• Programmable parameters through the PD14 programmer:
• recounting of indications (individual characteristic),
• two alarms of OC type operating in 6 working modes,
• display colour programmable in three intervals,
• thresholds of displayed overflows,
• highlight of the unit,
• automatic or manual compensation: temperature of cold junction (for J, K) or wire resistance (for Pt100),
• measurement averaging ti me.
• Supply of object transducers
