Synectic SY057 User manual

SY057
Encoder Splitter
User Manual
Rev. 3 14th October 2014

Description
SY057 provides a convenient way of splittin a master encoder si nal across multiple drives
or motion controllers. Its compact desi n and technical features makes it a perfect solution
for sendin material encoder solutions to more than one device.
The encoder input is switch selectable for operation with either standard RS485/RS422 with
differential TTL or HTL si nals, Differential volta e or sin le ended pulse.
SY057 unit as shipped
Special features
SY057 Expands the output from one shaft encoder to 4,8,12 or 16 individually
isolated encoder si nals.
SY057 doesn’t require direct electrical connection between the input and any of the
output encoder roups.
Every encoder roup of si nals can operate on a separate power supply
SY057 reduces the noise in the output si nal due to the absence of lon cable runs.
Plu in Screw terminal wirin
Piano style DIL confi uration switches

The following figure shows a block diagram e plaining the principle of
operation and the potential conditions between the circuits

Cascading several units
The number of outputs from the SY057
can be increased in blocks of 4, up to 32,
by addin 4 channel expansion modules
to the master unit. The expansion
modules can be identified as havin no
power in or input encoder connections.
They link to the master unit via 5way
expansion links provided with each
expansion module.
