Connector Pin Diagram
The connection of the sensors is done by screw terminals, optional digital I/O connections by push-clamp terminals.
With the push key below, the battery charging state can be checked. With the push key above, the measuring core BX6-CPU can be powered on/off (if configured by software).

The active strain gauge R3 is connected in 3-wire technology to the terminals Ud+, QB and -Us. The internal half-bridge R1, R2 is activated with a bridge connection from HB to Ud-.
When using quarter bridges of 120 or 1000 Ohms, solder jumper(s) must be changed for the appropriate channel(s). By default, quarter bridge is set to 350 Ohms. Only one of the three solder jumpers for quarter bridge completion must be closed for each channel, the other two must be left open.
| VOLTAGE INPUT UE 0-10V |
| FUNCTION | CH 1 | CH 2 | CH 3 | CH 4 | CH 5 | CH 6 |
| INPUT GROUND (Us-) | - | 2.2 | 3.2 | 4.2 | 5.2 | 6.2 |
| VOLTAGE INPUT UE | - | 2.7 | 3.7 | 4.7 | 5.7 | 6.7 |
The analog input UE (single ended) measures voltages 0 – 10V with respect to the US. The potential of US corresponds to the potential of the negative battery voltage. Single-ended inputs are only available for channels 2-6.
The cable shield can be connected to 1.8 – 6.8. With the module version it can be connected to the minus pole of the battery or charging connector (Pad 7).
