MUX-FB-12: twelve full-bridge transducers onto one CAN bus
The MUX-FB-12 takes twelve full-bridge strain gage transducers in 4-wire connection, two per M8 8-pin connector. Each channel has its own amplifier: 4.5 V ratiometric excitation, ±36 mV input range with gain and bridge balance set by software, 16-bit digitization, and positive and negative shunt calibration through an integrated 100 kΩ resistor. Output: CAN 2.0 up to 2 ksps, CAN FD up to 8 ksps on all twelve channels, 1.6 kHz at −3 dB. Supply 10 to 36 V DC; −40 to 85 °C; IP67 with the stacking connectors.
The module ships with its sensor cables, a setup cable for power and CAN, and the MUX Tool software for Windows. Over a PEAK-System USB-to-CAN adapter, the software configures each channel, records one module to a PC and generates the DBC file for a data recorder. Up to four modules stack, without cables between them, for 48 synchronized channels.
On a rotating part, the SR10AW/WFT slip ring and its 1024 ppr encoder mount on the stack through the MUX-ENC-ADA adapter layer; encoder position and speed come out with the module data. On a fixed part, the MUX-CON-ADA-NS adapter layer takes the power and data cable.
