Multiplexers

The 4WFB120 is compatible with our multiplexers.

Data Logger Considerations

The 4WFB120 is measured with the BrFull Instruction in CRBasic, and with Instruction 6 (Full Bridge) in Edlog. The 4WFB120 uses one differential analog input; an adjacent analog ground channel accepts the "ground prong" of the 4WFB120. Not all data logger terminal strips have this sequence on all channels, so please check your data logger's wiring panel to confirm channel assignments, especially if you plan to use multiple Terminal Input Modules.

The 4WFB120 is not compatible with the CR200(X)-series dataloggers. The lead wire that emanates from the head of the 4WFB120 connects to a data logger excitation channel.

Please note that if a CR10X will be used to measure thermocouples in the same application, newer CR10X Wiring Panels and the CR10XTCR Reference Thermistor (with its accompanying Thermocouple Cover) are deep enough to cover the data logger input channels with a Terminal Input Module attached; older CR10TCRs are not deep enough.
