LUMEL N30U Programmable panel meter of temp., resistance, V and A

• 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
