Introduction
Dear valued Customer!
Thank you for purchasing and using a product from our com-
pany. The compact universal controller UR3274U integrates
in a single device multiple options for sensor reading and
actuators command in addition to the extended supply range
24 to 230 Vac/Vdc. With 17 selectable sensors and outputs
congurable as relay or SSR command the user can reduce
stock needs.
The series includes also a model with serial communication
RS485 Modbus RTU. The possibility to repeat parametrization
is simplied by the programming module with internal batte-
ry that do not require power supply for the controller
For getting the highest eort out of this unit, we kindly ask
you to follow the below mentioned instructions:
Every person who is involved with the installation or usage of
this unit, must read carefully and understand the installation
manual and safety instructions!
 Safety instructions
. General instructions
To ensure the safe operation of this unit the instructions that
appear in this manual must be strictly observed. In addition,
when used all applicable legal and safety regulations for the
respective application must be observed. The same applies
correspondingly to the use of accessories.

. Intended Usage
Units from the controller series UR3274U are used for di-
splaying and monitoring of process values. Any other use is
regarded not in accordance with the intended usage.
Units from the controller series UR3274U are not meant to be
used as sole safety means to prevent dangerous situations on
machinery and installations. Machinery and intallations must
be so designed that fault conditions can not lead to harmful
situations to operating personnel (e.g. by independent limit
value switches, mechanical locking etc.).
. Qualied personnel
Units from the controller series UR3274U must only be
operated in accordance with the technical specications by
qualied personnel. Personnel regarded qualied is familiar
with the installation, assembly, putting into operation and
operation of the units and possesses adequate professional
qualication for the task.
. Remaining hazards
Units from the controller series UR3274U are state of the art
and safe to operate. A risk of danger can occur when deplo-
yed and operated improperly by untrained personnel.

6 UR3274U - User manual
In this manual remaining hazards are marked by the following
warning symbol:
This symbol indicates that non-observance of the
safety guidelines may cause hazards to persons
even serious injury or death and/or the possibility
of property damage.
