Outdated product since 2009, replaced by SACO 16D1/SACO 16D3/SACO 64D4
The relay subrack type SACO 128R4 is an extension rack used in association with the annunciator units SACO 64D4 and SACO 148D4 to increase the number of available output contacts for group alarms or individual realarm of alarm channels. Typical applications include separate annunciator lamp panels and annunciator applications requiring a separate output contact from each channel.
If the signals from the SACO 64D4 and SACO 148D4 need to be grouped before they are routed to the relay subrack SACO 128R4 this can easily be done with the signal grouping unit SACO 64C5.
The relay unit is a member of SPACOM, the ultimate integrated secondary equipment system for power systems.
