Product Description
Application
Range
The AMI Codes-II O3 analyzer is a complete monitoring system for
the automatic, continuous measurement and dosing control of ozone
based on the DPD colorimetric method according to DIN 38408-
3:2011-4.
It can be used for measuring ozone in pharma water and industrial
high purity water applications.
Signal
Outputs
Two signal outputs programmable for measured values (freely scale
-
able, linear or bilinear) or as continuous control output (control pa
-
rameters programmable).
Current loop:
0/4–20 mA
Maximal burden:
510 Ω
Third signal output available as an option. The third signal output can
be operated as a current source or as a current sink (selectable via
switch).
Relays
Two potential-free contacts programmable as limit switches for mea
-
suring values, controllers or timer for system cleaning with automatic
hold function. Both contacts can be set as normally open or normally
closed with a jumper.
Maximum load: 1 A/250 VAC
Alarm Relay
One potential free contact.
Alternatively:
Open during normal operation, closed on error and loss of
power.
Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values and in
-
strument faults.
Input
For potential-free contact to freeze the measuring value or to inter
-
rupt control in automated installations (hold function or remote-off).
Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory. Overvoltage protection of inputs and outputs. Galvanic sep
-
aration of measuring inputs from signal outputs.
