Programmable digital meter of temperature, resistance and standard signals N31U



The N31U meter is a new programmable digital panel meter destined for the measurement of standard analog signals used in automation. It is equipped with a modern high-contrast LCD display and allows simultaneous reading of two measured values. The meter is distinguished by its universal
power supply and 24V auxiliary output.

The meter's functionality is complemented by an RS-485 digital interface and a programmable alarm output to control the measured parameter. Programming parameters can be realized with the use of buttons, via RS-485 interface and free eCon software.

Programmable input:

  • temperature Pt100, Pt1000, J, K, N, E, R, S
  • resistance 400Ω, 4000Ω
  • current: ±20mA
  • voltage: ±10V, ±60mV, ±150mV, ±300mV
  • potentiometric transmitter


  • 1 x relay NC
  • 1 x auxillary supply 24V d.c./24 mA
  • 1 x RS-485


  • Universal input for measuring: temperature, resistance, standard signals
  • Two-line LCD display with high contrast and built-in backlighting
  • Possibility of displaying the measured value and time simultaneously or an uncalculated quantity or unit (programmable unit of measured quantity)
  • Meter programming from keyboard or through the RS-485 interface by means of the free eCon software.
  • 1x alarm output with signaling on led diode, working in 7 different modes
  • Memory of minimal and maximal values for all measured quantities
  • Supply of object transducers 24V d.c.
  • 32-point individual characteristic for the measured value
  • Mathematical functions for converting the measured value.
