Control data communicator SACO 148D4

Not active product since 2009

The combined control data communicator and annunciator type SACO 148D4 constitutes the master unit of the coordinated substation secondary equipment system SPACOM. The communicator part of the equipment, i.e. SACO 100M, controls the flow of information between the SPACOM devices of a substation, power plant or other installations and a superior control, monitoring or reporting system.

The communicator can also control a printer or another output device for local event output. The annunciator part of the equipment handles the standard field contact supervision in the application concerned. If required, the annunciator part can be extended with the necessary number of SACO annunciator units to obtain the desired capacity of the system.
