6.6 4-20 mA, Current Loop Output
The current loop option replaces the voltage output of the instrument with an isolated 4-20 mA
current output. The current outputs come out on the same terminals that were used for voltage
outputs, see Figure 2-2. The REC and DAS outputs have current loop capabilities. See
Troubleshooting Section 9.3.4.4 for electrical specifications and refer drawings 01471I and 01248I
for the jumper settings.
6.7 Status Output
The status output is an option that reports Analyzer conditions via contact closures on the rear panel.
The closures are available on a 50 pin connector on the rear panel. The contacts are NPN transistors
which can pass 50 ma of direct current. The pin assignments are listed in Table 6-3 below.
