The redundancy switch ("changover"), is 8 independent 2x1 relay switches in one housing. The switch supports CVBS, HD/SD-SDI and DVB-ASI signals.- The switching of signals is asynchronous and without state memorisation.- In case of network power failure the "Com" outputs are connected to the "A" inputs.- The switch is remotely controlled via Ethernet or GPI signals, locally - by a button on the front panel. When the local button is pressed, all channels are switched at once, while the remote control allows channel-by-channel switching.- The device has two power supplies.
