Order information
Lowside (negative; 0V) switching Version: UEA.1 Version 1.1Highside (positive; +24V) switching Version: UEA.2 Version 1.1
Difference UEA.1 - UEA.2: Integrated circuit I3 has 2 pins less on UEA.1 compared with UEA.2, so that a white frame from the component print on the PCB can be seen to the left of circuit I3 (see red frame in the pictures)
Characteristics
- PIC18 microcontroller with internal Flash (32kByte), RAM (1536 Byte) and EEPROM (256 Byte)
- integrated CAN controller
- CAN interface with high-speed driver according to ISO11898 without 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
Note: Not recommended for new installations
