N20 Digital Panel Meter

The N20 meter is a digital programmable panel instrument destined for measurements of d.c. voltages or d.c. currents: unipolar or bipolar, temperature through thermocouples (J, K) and Pt100 resistance
thermometers. The readout field is a LED display which enables the exposition of results in red, green or orange colours. The LPCon program is destined for the configuration of the N20 meter. The N20 meter must be connected to the PC computer through a PD14 programmer.
Following parameters can be reprogrammed:
– display colour, individually in three intervals,
– thresholds of displayed overflows
– display precision of the result (decimal point),
– highlight of the unit,
– automatic or manual compensation: temperature of ends in measurements with thermocouples, or wire resistance in Pt100 measurements,
– averaging time of the measurement,
– recalculation of indications (individual characteristic),
– two alarms of OC type operating in six working modes.
The alarm output switching on is signaled by the highlight of the triangular alarm index situated at the left display side, for the suitable alarm digit. The highlight colour is always different from the colour of the displayed (measured) value. The meter has a galvanic separation between the supply, measuring inputs and the programmer input. The protection level from the frontal side is IP65. Meter overall dimensions: 96 ´ 48 ´ 64 mm (including terminals).

Description

Parameters of the N20 meter:

  • input:
    – d.c. current: 0/4…20mA; ±20mA
    – d.c. voltage: 0…60mV; 0…10V; ±10V
    – temperature: Pt100, J, K
  • 2 alarm outputs of OC type (4 types of alarms) signaled by highlight of the alarm index,
  • protection level ensured by the housing: IP65,
  • readout field: 5 three-colour LED displays of 14 mm height,
  • highlighted measuring units,  
  • supply: 85…253 V a.c./d.c. or 20…40 V a.c./d.c.
  • overall dimensions: 96 x 48 x 64 mm.

For the configuration of the N20 is destined LPConfig program. The meter must be connected with the PC computer through a PD14 converter.
Parameters which can be reprogrammed are as follows:

  • display colour, individually in three intervals,
  • thresholds of displayed overflows,
  • display precision of the result (decimal point),
  • highlight of the unit,
  • kind of the measured signal a.c. or a.c. + d.c. (True RMS),
  • averaging time of the measurement,
  • recounting of indications (individual characteristic),
  • two alarms of OC type operating in six working modes.
