3.3.1.4. CURRENT LOOP ANALOG OUTPUTS (OPTION 41) SETUP

If your analyzer had this option installed at the factory, there are no further connections

to be made. Otherwise, it can be installed as a retrofit for each of the analog outputs of

the analyzer. This option converts the DC voltage analog output to a current signal with

0-20 mA output current. The outputs can be scaled to any set of limits within that 0-20

mA range. However, most current loop applications call for either 2-20 mA or 4-20 mA

range.

Figure 3-10 provides installation instructions and illustrates a sample combination of

one current output and two voltage outputs configuration. Following Figure 3-10 are

instructions for converting current loop analog outputs to standard 0-to-5 VDC outputs.

Information on calibrating or adjusting these outputs can be found in Section 5.9.3.7

CAUTION – AVOID INVALIDATING WARRANTY

Servicing or handling of circuit components requires electrostatic

discharge protection, i.e. ESD grounding straps, mats and containers.

Failure to use ESD protection when working with electronic assemblies will

void the instrument warranty. Refer to Section 14 for more information on

preventing ESD damage.
