The SW-1621HV-REL redundancy switch ("changover" in English terminology) is 16 independent 2x1 relay switches in one housing. The switch supports HD/SD-SDI, DVB-ASI and CVBS signals.- The switching of signals is asynchronous and without state memory.- 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.
