LED display controller - Y5WLED2, Y12WLED2

  • possibility to controll 2 LED displays (8 digits) 

  • digits height up to 57 mm 

  • multiplexed controll of LED segments 

  • small size and possibility of easy install on standard bus 

  • power supply 12V DC 

  • interface RS-485 (half-duplex) 

  • MODBUS protocol (or others)

  • possibility of easy addressing up to 127 identical controllers

Structure:
Y12WLED2 contains:
· output unit - elements controll LED segments
· main unit - based on AT89C51 microcontroller - reads coded data and display it on LED displays

Use:
Y12WLED2 displays any information by digits and others characters. It's a part of digital clocks or meters of temperature, pressure, voltage, frequency and others. It may also cooperate with data networks as display unit (measurment values and others).

Communication:
Datatransfer with controller is realised with RS-485 port. It use standard MODBUS RTU protocol.
