load cell configuration

[saeed1812003]

Hello,

I want to wire a load cell (type HBM RSC-2K 2555) to SSC-SG24 module.

Can you please guide me how to do this?

Based on the manual for the load cell the wire colors are:

Blue - Ex+

Black - Ex-

Green - Sense+

Grey - Sense-

White - Signal+

Red - Signal-

Wire - Shield

Based on the SG24

Terminal1 - Ex-

Terminal2 - Ex+

Terminal3 - Signal2-

Terminal4 - Signal2+

Terminal5 - Signal1-

Terminal6 - Signal1+

Black wire goes to Terminal1

Blue wire to Teminal2

Red wire to Terminal5

White wire to Terminal6

You do not use the Sense lines or terminals 3 and 4.

The Shield wire should be connected to ground if you have noise problems.

Thanks a lot,

According to its datasheet, the loadcell type RSC-2K 2555 requires an excitation
voltage of 18 volt, but the signal conditioner I'm using (NI SSC-SG24)
generates an excitaion of 10 volt.
I think that is why I still  cannot connect loadcell to DAQ.

The load cell does not require 18V. 18 Volts is the maximum excitation you can apply without overheating or possibly destroying the strain gages that are built into the load cell. You can use a lower voltage, that is why the output is quoted in mv/V, which is the number of millivolts output at maximum load per volt of excitation. 10 volt excitation will provide a maximum of 20 mv output at maximum load.You will notice in the SCC - SG24 specifications that it is designed for 350 ohm full bridge strain gages which is what your load cell uses.
