2 -wire Loop Powered Display  LCDD-03
Performance
All transmitters with an output signal 4 to 20 mA
Feature
* The LCDD-03 display is fit for all of the transmitters and converters with 4-20mA 2-wire technique, just as pressure,
differential pressure, temperature, flow, PH, acceleration, and so on.
* 16 bit ADC MCU inside.
* Customer can use the three buttons to program the zero, span, decimal point, damping and alarm point, etc.
* Over or under range is displayed as a message. The integrated smart diagnostic system continuously monitors
all device functions.
* The programmed parameters are stored in an EEPROM and are kept in case of a power failure.
* The LCDD-03 can indicate the current measurement value input in per sent through bars meter.
* Many kinds of the units can be displayed, such as mA, us, PH, mbar, etc.(Further versions are possible on request.)
* The LCDD-03 display is powered by the current loop of the 4 to 20 mA signal transmitter. No additional auxiliary
power is required.
* Optional: two OPTO switch output
Easy programming with push buttons
Reverse polarity
Low power consumption
LCD can work at 3mA
Optional: two OPTO switch output
