SD-SDI CHANGEOVER SWITCHER WITH CLEAN SWITCHING

SD-SDI CHANGEOVER SWITCHER WITH CLEAN SWITCHING

The SAC6840N is a 2X1 SD-SDI/ASI auto changeover. The Changeovers are performed by SAC6840N internal electronic switch with clean switch supporting. The signal is protected by the relays on SAC6840N rear panel when power failure, and maintaining the selected signal at the output.

The input can be selected automatically or manually. Automatic signal selection is based on internal signal alarm status monitoring. An optional remote control panel can be chosen for manual control.
