Notes:

When connecting one full-bridge sensor, connect the positive pole of the sensor excitation power supply to E+, the negative pole to E-, and the shield to SH. Signals are connected to S1+ and S1-. Pay attention to signal polarity.
When connecting two full-bridge sensors, connect the positive poles of the sensor excitation power supply in parallel to E+, the negative poles in parallel to E-, and the shields in parallel to SH. Signals are connected to S1+, S1-, S2+, S2-. Pay attention to signal polarity.
When connecting two half-bridge sensors, connect the positive pole of the sensor excitation power supply to E+, the negative pole to E-, and the shield to SH. Signals are connected to S1+ and S1-. Pay attention to signal polarity.
