SynchLink Base Block 3

SynchLink Overview

We designed the SynchLink system to provide the synchronization and coordination
of drive and motion control applications that are based on ControlLogix™ and
PowerFlex 700s™ stations.

About the SynchLink Base Block

The base block converts optical signals coming from a SynchLink station to
electrical signals, and then re-times and retransmits them simultaneously to a
maximum of four 4-port splitter blocks. It also supplies power to splitter blocks.
The base block requires a 24V dc power supply. The power supply connection is
made via field wiring to a screw connector plug. The base block is DIN
rail-mounted and is housed in a two-piece plastic enclosure. Figure 1 identifies the
components of the base block.

Prevent Electrostatic Discharge

Electrostatic discharge can damage integrated circuits or
semiconductors if you touch backplane connector pins.
Follow these guidelines when you handle the base block:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the backplane connector or connector pins.

• Do not touch circuit components inside the base block.

• If available, use a static-safe work station.

• When not in use, keep the base block in its static-shield

box.

Installing the Base Block

To install the base block on the DIN rail:

1. Position the base block on the 35×7.5mm DIN rail (Allen-Bradley catalog

number 199-DR1) at a 30° angle.

2. Hook the lip of on the rear of the base block onto the top of the DIN rail

and rotate the base block onto the rail.

3. Press the base block down to the DIN rail until flush.

The locking tab should snap into position and lock the base block to the
DIN rail. If the tab does not snap into position, follow step 4. If the tab does
snap into position, proceed to step 5.
