Input System Specications
Aux Systems
ere are 6 Aux input systems that allow digital or analog (0-
1.0VDC, 0-5.0VDC, or 4-20mA) conguration. In addition, four
of the Aux systems can be congured as temperature systems see
Temperature Systems Specs - page 15.
Aux System Type Digital Analog
Range dry contact open/close 0 -1.0 VDC, 0-5.0 VDC, or 4-20mA
Accuracy n/a 0-1.0VDC: ± 3% ± 10 mV
0-5.0VDC: ± 3% ±15 mV
4-20 mA: ± 3% ±100A
Resolution n/a user selectable (0), (0 .0), or (0.00)
DO Systems
ere are up to 4 independent DO systems. Each DO system has
2 control ranges, 2 control ranges, and high and low alarming.

aer the DO sensor is serviced,
for the polarographic sensor to
stabilize.

Temperature
Systems
ere are 4 independent temperature systems. Auxiliary inputs
3, 4, 5, & 6 can be congured as temperature systems. Each tem-
perature system has 1 control range, 1 control  range, and high
and low alarming. Temperature systems can be congured as the
temperature source for DO measurements on a 5400 or as stand
alone systems on either 5400 or 5500 instruments..
