ABB DIGITAL ANNUNCIATOR UNIT SACO 16D3 NUMERICAL RELAY

Digital annunciator unit SACO 16D3 Numerical relay – The SACO 16D3 is used in a variety of applications requiring supervision of alarm and signalling contacts in power plants, substations and industrial process installations. The SACO 16D3 is a flexible, field-customizable 16-channel digital annunciator unit. It is used in a variety of applications to supervise alarm and signalling contacts in power plants, substations and industrial process installations. The alarm unit is also approved for use in offshore installations and marine applications. Further, the annunciator unit can be used in any application where on/off signals are to be supervised. This annunciator unit provides immediate fault recognition, fault identification and visual and audible alarm when an abnormal process situation occurs. The annunciator unit also provides a means for subsequent fault analyses, which means that corrective measures can be carried out without delay and full control of the process can be maintained. The SACO 16D3 annunciator units can be used either as independent stand-alone units, or they can be connected together via a fibre-optic bus to form complete supervision, event sequence reporting and data acquisition systems.
