2.7.13 Analog I/O Connections
(User Wired in Controller Box or Junction Box)
There are (2) 4-20ma inputs and (8) 4-20ma outputs
available in the 3D TRASAR controller. Both are
non-isolated
.
The analog inputs must be externally powered. They can be used to control conductivity
, pH, and
ORP. Refer to Appendix I for information on the halogen analyzer.
The analog outputs are internally powered for a max. load of 600 ohms. The analog outputs can be
used to transmit any of the following variables:
TRASAR product dosage, Tag Polymer product
dosage, Cell Fouling, Nalco Scale Index, Nalco Bio-Index, Conductivity, pH, ORP, Corrosion
#1, Corrosion #2, and Sample Water Temperature
.
