SRcb
–
Ripple-control checkback receiver for DIN-rail mounting
The SRcb is a state-of-the-art, Swistra-compatible audio-frequency ripple-control receiver
designed for DIN-rail mounting.
Thanks to the SRcb, incoming data from ripple-control telegrams and audio frequency levels
can be
recorded at any given location in the grid. All relevant data will reliably be stored locally and can be
downloaded to laptop or PC via RS232-interface. Thus, the data can be used for analysis purposes and
even be edited via MS Office. Due to its modularity, the SRcb can be used everywhere and can easily be
extended.

Technology
All Swistec ripple-control receivers use state-of-the-art, recently developed filter algorithms capable of
reliably processing ripple-control signals with operating voltages <0.3% Un – a result of state-of-the-art
processor technology combining high CPU power with little power consumption.
