INTRODUCTION
The Linearized RTD/TC module is flexible for DIN rail
mounting and is easily installable. The module has wide
input & output ranges, which are field selectable & factory
settable as per customer requirement respectively.
SAFETY AND WARNING NOTES
To minimize potential shock, turn off power to module
installed in the base before inserting or removing a
module.
In order to make safe operation of the device and to be
able to make use of all the functions, please read these
instructions thoroughly!
The device may only be installed and put into operation by
qualified personnel.

INSTALLATION GUIDELINES
This Module is suitable for mounting on 35mm DIN
Rail. Note the polarity when connect field wire.
The (horizontal) mounting arrangements shown here,
allows good vertical air circulation. It is also recommended
to keep adequate gap between two modules.
