GUIDE TO INSTALLATION AND OPERATION

4 | SDA-1401

Panels are available for the Densité 2RU frame, and also for the Densité 3RU

frame. The 3RU versions are identified by the number 3 in the size designator

portion of the part number, e.g.

• SDA-1401-SRP is a 2RU version

• SDA-1401-3SRP is a 3RU version

Panels denoted by the suffix –R incorporate a bypass protection relay, as described

in the next section.

2RU panels are available for the 1x4 configuration (single-width rear) and the 1x9

configuration (double-width rear)

3RU panels are available for the 1x7 configuration (single-width rear)

• 2RU panels can be mounted in the 3RU frame if required, using mounting

adapter hardware.

The SDA-1401 detects the type of rear that is installed, and configures itself

accordingly.

In all cases, the rear panel includes:

• ASI IN – one input on a BNC connector

• ASI OUT – the appropriate number of outputs (4, 7 or 9) on BNC connectors

2.4 Bypass Protection Relay

A bypass protection relay is mounted on the SDA-1401-SRP-R, SDA-1401-DRP-R and SDA-1401-3SRP-R

rear panels.

The 1

output BNC is tied to the input via the non-latching relay which receives its power from the SDA-1401

card. The relay will trip upon detection of loss of card power, either through supply failure or removal of the

card from the Densité frame.

The relay enables the following functions

• Bypass the electronic circuit

• Protect the output when power is lost

• Protect the output when card is removed from the frame
