PRESSURE DIGITAL DISPLAY TYPE LEDD-010 pages

PRESSURE DIGITAL DISPLAY TYPE LEDD-01 FEATURES: - Pressure indicator - 4 digit display - Plug and play - Self powered - Optional two OPTO alarms - LED can work at 3mA - 16 bit ADC MCU inside - Reverse polarity DESCRIPTION: The plug-on display LEDD-01 is fit for all transmitters and converters with 4-20 mA wire technicquejust as pressure, differential pressure, temperature, flow, PH, and so on. Customer can use the two buttons to program the zero point, span, decimal point, damping and alarm point etc. Over or under range are displayed as a message. The integrated smart diagnostic system continuosly monitor all device functions. The programmed parameters are stored in an EEPROM and being kept in case of a power failure. The plug-on display is simply plugged in between connector and socket; it is then ready for operation. The plug-on display id powered by the current loop of the 4 to 20 mA signal transmitter. No additional auxiliary power is required.
