Order information

Lowside (negative; 0V) switching Version: UEA.1 Version 2.0
Highside (positive; +24V) switching Version: UEA.2 Version 2.0


  • PIC18 microcontroller with internal Flash (32kByte), RAM (3648 Byte) and EEPROM (1024 Byte)
  • integrated CAN controller
  • CAN interface with high-speed driver according to ISO11898 with galvanic isolation
  • ICSP interface for In-Circuit-Programming (Software download)
  • 8 inputs and 8 outputs, always 1 input and 1 output onboard connected
    • UEA.1: lowside switching inputs and outputs
    • UEA.2: lowside switching inputs and outputs
  • Even if always 1 input and 1 output are connected together the may be used for different functions at the same time, because every active output is switched off every 9ms for 3ms (pulsed output) to enable reading of the input in this time. Example: Input used as car call, output used as level indicator
