Services Available
Repair No
Calibration No
Free Support No

Overview

The 4WFBS1K replaced the 4WFB1K on June 19, 2009.  The 4WFBS1K provides the same functionality as the 4WFB1K, but the new module has two external pins that allow customers to perform shunt calibrations.

Additional Compatibility Information

Multiplexers

The 4WFB1K is compatible with our multiplexers.

Datalogger Considerations

The 4WFB1K is measured with either CRBasic's BrFull Instruction or Edlog's Instruction 6 (Full Bridge). The 4WFB1K uses one differential analog input; an adjacent analog ground channel accepts the "ground prong" of the 4WFB1K. Not all datalogger terminal strips have this sequence on all channels, so please check your datalogger's wiring panel to confirm channel assignments—especially if you plan to use multiple Terminal Input Modules. It is not compatible with the CR200(X)-series dataloggers. The lead wire that emanates from the head of the 4WFB1K connects to a datalogger 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 datalogger input channels with a Terminal Input Module attached; older CR10TCRs are not deep enough.
