ABB Digital Annunciator Unit SACO 16D1

SACO 16D1 is a flexible digital annunciator unit for the supervision of

alarm and signalling contacts in power plants, substations and industrial

process installations.

The SACO 16D1 is a flexible, field-customizable 16-channel digital

annunciator unit. It is used in a variety of applications to supervise alarm

and signaling 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 sophisticated hardware and software self-supervision system to ensure

maximum operational reliability has been designed for also the most

demanding environmental conditions.  The SACO 16D1 provides immediate

fault recognition, fault identification and visual and audible alarm when an

abnormal process situation occurs.  The alarm channels are activated by

normally open or normally closed contact. This annunciator unit also provides

a means for subsequent fault analyses, which means that corrective measures

can be carried out without delay and you maintain full control of the process.

The first-out alarm indication is achieved via a clear four-digit display on the

front panel.

The annunciator units can be used 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.
