ABB Digital annunciator unit SACO 64D4

SACO 64D4 is a self-contained microprocessor-based annunciator

unit with 64 alarm channels. It is used in a variety of applications

requiring supervision of alarm and signalling contacts in power

plants, substations and industrial process installations.

The SACO 64D4 is a self-contained microprocessor-based annunciator

unit with 64 alarm channels. 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.

The annunciator unit provides immediate fault recognition, fault

identification and visual and audible alarm in an abnormal process

situation. The 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 annunciator units can be used as independent stand-alone units,

or several units can be interconnected and connected to printers,

terminals, etc., to form complete supervision, event sequence reporting

and data acquisition systems. The maximum annunciator system capacity

is 560 channels in one system and the resolution of the time marking is

10 milliseconds.
