ABB DIGITAL ANNUNCIATOR UNIT SACO 64D4 NUMERICAL RELAY


ABB DIGITAL ANNUNCIATOR UNIT SACO 64D4 NUMERICAL RELAY

SACO 64D4 Numerical Relay 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.

Scope

Self-contained microprocessor-based annunciator unit with 64 alarm channels

Product benefits

Centralized alarm panel

Product features

  • Sixteen output relays: 14 for group realarms, one for an audible device and one for the self-supervision system

ABB Numerical relays

ABB Numerical relays are based on the use of microprocessors. A big difference between conventional electromechanical and static relays is how the relays are wired. Electromechanical and static relays have fixed wiring and the setting is manual. Numeric relays, on the other hand, are programmable relays where the characteristics and behavior can be programmed. Most numerical relays are also multifunctional.
