Description: Photometric measuring system for detecting absorbance or
turbidity in liquids and gases.
Sensors, consisting of light transmitter and receiver, are
installed in an armature which is then installed in the piping
system.
Voltage supply of the light transmitters is 5 V.
XYZ in the type designation stand for number of optek sensor
inputs (X), number of interface inputs or interface types (Y)
and number of lamp outputs (Z).
Haze and Fermenter variants differ in inscription details and
an additional resistance in the output circuit of the lamp
supply.
Interface cards: IO 24 for SELV/PELV-supplied system busses
IO 12 with 2 conventional current inputs and 7 remote inputs
in the SELV range
