Analog annunciator unit SACO 16A3

Not active product since 2009

The analog annunciator unit is used in a variety of applications requiring monitoring of analog quantities such as temperature, current, voltage, power, etc. in power plants, substations and industry. The equipment is also used in off-shore installations. For temperature measurement standard Pt or Ni sensors are used. For measuring electrical quantities measuring transducers with standard mA or V outputs are employed.

The annunciator units can be used as independent stand-alone units, or they can be integrated via a fibre-optic bus to form complete supervision, event sequence reporting and data acquisition systems.
