3. Brief description
The signal isolator
SIRAX SI 815
serves to electrically in-
sulate 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 SIRAX SI 815 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.
