Thank you for choosing a Pixsys controller.
Controller DRR245 is specifically conceived for application on control
panels with DIN rail mounting.
Pixsys makes available in a single device all the options relevant to
sensor input and actuators command, in addition to the extended
power range 24…230 Vac/Vdc. With 18 sensors to select and outputs
configurable as relay, SSR command, 4…20 mA and 0…10 Volt, the
user or retailer can reduce warehouse stock by rationalising investment
and device availability.
The series is equipped with serial communication RS485 Modbus RTU
and with a loading control function via the amperometric transformer.
The configuration is further simplified by the Memory cards which are
equipped with internal battery and therefore don’t require cabling to
power the controller.

5.1 Wiring diagram
Although this controller was designed to resist
noises in industrial environments, pease notice
following safety guidelines:
• Separate the feeder line from the power lines.
• Avoid placing near units with remote control
switches, electromagnetic contactors, high
powered motors and in all instances use
specific filters.
• Avoid placing near power units, particularly if
phase controlled.
