1. Read fi rst 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
7. Mounting
8. Electrical connections
are observed.
The device should only be handled by appropriately
trained personnel who are familiar with it and authorised
to work in electrical installations.
Unauthorized repair or alteration of the unit invalidates
the warranty!

3. Brief description

The signal isolator SINEAX SI 815-1 serves to electrically
insulate the 4...20 mA input circuit of a two-wire transmitter.
It performs two tasks at the same time. Firstly it provides
electrical insulation and secondly it conducts the power

supply needed for measurement to the two-wire transmitter
without injecting into the circuit itself. Thus the isolator does
not require an power supply connection itself.
Some versions of the SINEAX SI 815-1 are designed for FSK
communication. They are used in conjunction with "intel-
ligent" two-wire transmitter which are capable of dialogue
and operation according to the FSK principle and the HART
or user-specifi c protocol.
The series also includes "intrinsically safe" versions
[EEx ia] IIC with an intrinsically safe measurement/supply
circuit. These operate in conjunction with intrinsically safe
two-wire transmitters located in explosion hazard areas.
