Application

The analog annunciator unit is used in a vari-
ety of applications requiring monitoring of 

analog quantities such as temperature, cur-

rent, voltage, power, etc. in power plants, 
substations and industry. The equipment is 

also used in off-shore installations. For tem-

perature measurement standard Pt or Ni sen-
sors are used. For measuring electrical 

quantities measuring transducers with stan-

dard mA or V outputs are employed.

The annunciator units can be used as indepen-
dent stand-alone units, or they can be inte-

grated via a fibre-optic bus to form complete 

supervision, event sequence reporting and 
data acquisition systems.
