2 -wire Loop Powered Display LCDD-03

2 -wire Loop Powered Display is a kind of transmitter with an output signal of 4 to 20 mA and an LCD display

The LCDD-03 display is fit for all of the transmitters and converters with the 4-20mA 2-wire technique, just as pressure,

differential pressure, temperature, flow, PH, acceleration, and so on.

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
