ICA5S & ICA5A Connections
The power supply for the ICA5S should be between 7.5 and 28 V
The minimum supply for the ICA5A version is 9 V
Please note that by design, the excitation voltage provided by a 2-wire load cell amplifier decreases as the load cell's
impedance decreases resulting in a reduction in the load cell's output. The lower signal level requires more gain from
the ICA5 to compensate leading to a degradation in performance with regards to temperature stability and noise
performance.
Impedances greater than 1000 ohms and sensitivities of 1 mV/V and higher are recommended.

The strain gauge cable should be attached to the solder pads as illustrated.

ICA5A
The securing bolt should be used to provide a good electrical ground and mechanical support. This is important for
optimum EMC performance.
