1. Read first and then ...
The proper and safe operation of the device
assumes that the Operating Instructions are
read carefully and the safety warnings given
in the Sections
5. Mechanical coding of the
plug-in module
6. Electrical connections
7. Mounting
are observed.
The device should only be handled by ap-
propriately trained personnel who are famil-
iar with it and authorised to work in electrical
installations.

3. Brief description
The signal isolator SIRAX TI 807 serves to electrically insulate
two or three analogue DC signals in the range 0...20 mA
which depending on version is then converted to a current or
voltage signal (0...20 mA or 0...10 V). It does not require a
separate power supply.
