Main / Changeovers (video, audio, SDI) / PRB-101

PRB-101 series relay bypass module is intended for commuting the PAL/SECAM, HD/SD SDI, stereo audio (analog or AES/EBU) signals providing an emergency bypass facility. The PRB-101A modification is for audio-only bypass commutation.
PRB-101(A) is controllable from its frontal panel and by external GPI commands.
The latching relay used for switching allows for resuming the selected state during the power down condition.
PRB-101(A) may be used as the 2x1 relay switch, in this case its OUT1 port is used as the main output, the INA and INB ports - as the two inputs. The GPO output reflects the "NORM/BYPASS" status.

PRB-101(A) is featuring the 1U case.

The «NORM» and «BYPASS» backlit buttons are located at the frontal panel.
