DC amplifier designed for strain gage measurement systems. SP4M (analog) When load cells in a six‐wire configuration are connected to amplifiers with a four‐wire configuration, the sense leads of the load cells must be connected to the corresponding excitation leads.
Please ensure that the inline amplifier and load cell are on the same electric potential, to prevent any compensating currents via the cable shield. The module has a short-circuit proof design but is not protected against overvoltages. SP4M, SP4Mi ELECTRICAL CONNECTION...

If the sensor connection cable is damaged, please send your measurement chain to HBK for repair. If you have selected the IO-Link option, the digital transducer electronics module with the IO-LINK interface, data output rate COM3 is installed.
The electronics continuously monitors the sensor so that you are warned if critical operating states occur. The data is transferred to the PLC in accordance with the IEC 61131-9 standard (IO-Link). The electrical connection is also defined in this standard. SP4M, SP4Mi IO-LINK OPTION (SP4Mi)
Typical latency times from the change in weight until analysis by a PLC are between 3 and 10 milliseconds (dependent, among other factors, on the IO-Link master, fieldbus and PLC being used) if the filters in the electronics are disabled. SP4M, SP4Mi IO-LINK OPTION (SP4Mi)
The process data is transmitted in accordance with the IO-Link Smart Sensor profile, 2nd edition, version 1.1. The exact format corresponds to the coding PDI48.MSDCF_1.

The system command can be used to trigger automatic taring. The device automatically switches to the net weight value as soon as the standstill condition is met. A switch to gross can be triggered by a second system command. The current tare value can be read out. SP4M, SP4Mi IO-LINK OPTION (SP4Mi)
Signal components above the set cut-off frequency are suppressed relatively quickly. The cut-off frequency may be between 3 and 30 Hz. IIR filters: These filters have a lower characteristic slope than the FIR filter. The cut-off frequency may be between 0.1 and 30 Hz. SP4M, SP4Mi IO-LINK OPTION (SP4Mi)

If the filtering is too weak, the interference will still be too high, and the scatter of the measurement values will be too wide, meaning the measurement uncertainty increases. SP4M, SP4Mi IO-LINK OPTION (SP4Mi)
