Connect to the 4–20 mA outputs
Figure 7 Device connection
Use twisted pair shielded wire for the 4–20 mA output connections.
Connect the shield at the recorder end or the analyzer end. Do not
connect the shield at both ends of the cable. Use of non-shielded cable
can result in radio frequency emission or susceptibility levels higher than
the allowed levels.
Refer to the installation manual to connect the device and for wiring and
load impedance specifications.
Note: The 4-20 mA outputs cannot be used to provide power to a 2-wire (loop-
powered) transmitter.
Install the 4–20 mA input and output module
Use this procedure to install the 4–20 mA input or output module in the
analyzer. Refer to Figure 8 for the module installation. Refer to Table 1
for the terminal assignments for the 4–20 mA modules.
