Outputs
The advanced option for the instrument provides two opto-isolated output
ports. Either or both can be used for 4-20 mA or pulse outputs.
CAUTION
Due to the dual-purpose nature of the outputs, take care not to
set the output as an open collector pulse type signal when
connected to a 4-20 mA loop circuit.
4-20 mA Output Connection
Figure 11 shows the connections for a 4-20 mA output. Output channel 1
uses terminals 27 (+) and 28 (-), output channel 2 uses terminals 29 (+) and
30 (-).
Maximum Load Resistance = (Supply-9) / 0.02 ohms
