2.8 Connecting the Load Cells
Information for connecting the load cells is given in the appendix for each load cell type, see
table below.
2.9 Connecting Analog Outputs (AO1-AO6)
There are six analog outputs. Each output can be set either for voltage or current. Each analog
output from the digital/analog converter is a voltage. This is split into two outputs, one of which
is converted into a current output and the other kept as voltage. This is illustrated in Figure 2-12
where for example X4:1 is the voltage output and X4:2 is the current output.
The allowed load current of the voltage output is max. 5 mA.
The allowed load resistance of the current output is max. 550 ohms.
Figure 2-12 shows AO1 connected for voltage output and AO2 for current output.
