3.3.2 Connecting the Analog Outputs
Two isolated analog outputs (1 and 2) are provided, see Figure 3-18. Each output
can be set to 0–20 or 4–20 mA, and can be assigned to represent the measured
parameter or secondary measurement such as temperature. Make connections
with twisted-pair shielded wire and connect the shield at the controlled component
end or at the control loop end. Do not connect the shield at both ends of the cable.
Use of non-shielded cable may result in radio frequency emission or susceptibility
levels higher than allowed. Maximum loop resistance is 500 ohm. Refer to the
sensor manual for output software setup.
Make wiring connections at the analyzer end as shown in Figure 3-18.
