Loop Powered LCD Indicator for In-head Mounting

LCD-H20 is a digital indicator for installation directly in a 4-20 mA loop
without need for external power. LCD-H20 is designed for in-head mounting in a sensor connection head with glass window.
The indicator is equipped with high-contrast, easy-to-read LCD digits.
The scale is easily programmable, without reference signal, by three pushbuttons for any values between -1999 and 9999.
As an option, LCD-H20 can be delivered mounted in a connection head.

  • Installation directly in a 4-20 mA loop without need for power supply
  • 2.5 V voltage drop
  • High-contrast, 4-digit LCD display with 12 mm digits
  • Simple pushbutton 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 0.1 % allows for high precision read-outs
  • HART transparent
  • Designed for ambient temperatures between -20 to +70 °C /-4 to +158 °F
  • Protection IP65 when mounted in connection head Type 1 or Type 2
