Product Description

The LEI-515B/GPI is designed to monitor its Main input signal and automatically switch to an Alternate signal if the Main signal is lost. A captive-screw terminal sub-module is provided for "audio-follow video" capability or status mode, which is switched internally. A three-terminal dry-contact connector offers normally-closed and normally open contacts to control peripheral gear.

The input receiver device monitors the incoming signal level and produces a DC voltage that is used to detect signal presence. This DC voltage is compared to a front panel user-set threshold voltage. If this DC voltage exceeds the threshold voltage, the LEI-515B will switch to its auxiliary input. This "sensitivity" adjustment gives the LEI-515B the ability to select its auxiliary input even before data errors are visible in the primary input.
