4x1 emergency switching for SDV

The ESW-41S is designed for applications requiring automatic
emergency switching capability in the event of signal loss. The
main program input in monitored and on loss of sync data, the
output is switched to the next available ¡®good¡¯ input after four
blank frames (or if the user wishes, the output can switch to black).

The automatic switching feature can overridden by the operator through external connection
to the GPI.

The program path is maintained, even in the event of a power failure, through the inbuilt
bypass relay. This connects input 1 to the main output.

In the event of power failure to the unit a passive bypass relay connects input 1
to the main program output.
