and 
the 
most 
conven
-
ient, as regards installation and configuration, digi-
tal or analog I/O extension for the PR200 Program-
mable Relay from akYtec.
This  module  connects  to  the  PR200  base  unit  di-
r
ectly 
over 
the 
inter
nal 
bus, 
which 
ensur
es 
much
faster  and  reliable  communication  as  compared 
to  RS485/Modbus.  Moreover,  the  communication 
over the internal bus requires no additional I/O con-
figuration as it is with Modbus r
egisters.
Functions and features:
•
 Independent power supply (24V DC or 230V 
AC on option)
• The same high-speed performance as that of 
the PR200 base unit
• Easy connection, removal and replacement
•
 Galvanic isolation between power supply and 
I/O groups
8 digital or 4 analog inputs
8 digital or 2 analog outputs
