A4000

The Quartzlock A4000 redundant switch is a 1U, 19” rack mount unit that switches automatically from a primary to a secondary source.

Inputs

There are four inputs on the rear of the instrument - two signal and two DC control. The inputs are a primary source (A) and a secondary source (B). These sources are switched, dependant on the control input, one for the primary (A) and the other for the secondary (B).

The control lines are 0 ~ 5v DC active high (+5v DC).

Output

There is one single signal output on the rear panel. This is the output from either signal input, dependant on the control input

Typical uses

The Quartzlock A4000 is installed in many remote, unmanned telecommunications base stations to ensure continuous time and frequency standards are available for mission critical applications.
