BAR Graph Display

BAR Graph Display

Quick Overview

The BAR-X and BAR-A are user friendly programmable process bar graph displays. The BAR-A is for display only, the BAR-X includes 2 alarm relays. Can accept most process signals such as 4-20mA, 0-10V, 1-5V, etc. Will power 2 wire transmitters with the standard 24V excitation supply, assuming sufficient power input.

Display almost any physical variable...
The bargraph displays on this page accept most common process signals such as 4-20mA, 0-10V, 1-5V etc. All can be scaled to read in your preferred engineering units.

Most have a 24V excitation output voltage which you can use to power a 2 wire or 3 wire input loop.

Suited for these applications and more:-

  • Level measurement - use a depth or level sensor
  • Pressure measurement - use a pressure transmitter sensor
  • Tank contents display - use a level sensor
  • Temperature measurement - use a temperature transmitter
  • Humidity measurement - use a humidity transmitter
  • Any physical variable having a 4-20mA or 0-10V signal
Input connections Current input, Voltage input, Excitation

Suits direct connection, 2 wire active or passive loop and 3 wire transmitter systems.
Input Signals Current input terminal accepts:-
0-10mA, 0-20mA, 4-20mA
33 Ohm input resistance
