LCD-H11X is a digital, heavy-duty LCD indicator for installation directly in a 4-20 mA loop without need for external power.

The indicator is equipped with high-contrast, easy-to-read LCD digits. The scale is easily programmable, without reference signal, by three push buttons for any values between - 1999 and 9999.
  • Can be used with any DIN B transmitter or as display only
  • Installation directly in a 4-20 mA loop without need for power supply
  • Only 1.5 V voltage drop
  • High-contrast, 4-digit LCD display
  • Simple push button scaling without reference signal
  • Any range between -1999 to 9999 for 4 to 20 mA input
  • Labels for different engineering units are included
  • Typical accuracy of 0.05 % allows for high precision read-outs
  • HART transparent
  • Designed for ambient temperatures between -25 to +70 ºC / -13 to +158 ºF
  • Field mounting in rugged IP 66 / NEMA 4X housing
  • 90º indexing of display orientation
