Overview
Encoder Buffer Unit
Description The Encoder Buffer Unit is a DIN rail mounting module designed to
duplicate the master incremental quadrature pulse train with index.
The device accepts the master incremental signals at connector P2,
buffers them, and makes a duplicate of them available on all follower
outputs.
Provided the format of the signal at the master input is TTL level
RS422, the Encoder Buffer Unit is not concerned about its source.
Therefore, an encoder (the master encoder) can be connected to this
input or other hardware items such as an ESRS (Encoder Signal
Reference Simulator) can be used.
Encoder Buffer Unit Principal Features

• Individually selectable 5V power to follower outputs.
•
Individual 5V and 12V power supply OK indicators.
•
Product housed in a rugged DIN rail mounting PCB tray with
integral mounting feet.
•
Powered from a single +24V DC supply.
