1. Application
The power supply unit EURAX B 811 (Fig. 1) provides the
DC power supply for 2-wire transmitters and transfers the
measured variable unchanged to the electrically insulated
output.
Conversion to a different signal range such as 0...5 mA or
1 ... 5 V (signal converter) is also possible.
Some versions of the EURAX B 811 are designed for FSK1
communication. They are used in conjunction with "intelli-
gent" 2-wire transmitters which are capable of dialogue and
operation according to the FSK principle and the HART or
user-specific 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
2-wire transmitters located in explosion hazard areas.
Provision is made for monitoring the measurement/supply
circuit to detect short and open-circuits. Either of these faults
is signalled by the fault signalling relay AF and the red LED.
The output signals A1 and A12 can be set on the DIP switches
to have a linear increasing or decreasing response.
The power pack fulfils all the important requirements and
regulations concerning electromagnetic compatibility EMC
and Safe Isolation (IEC 1010 resp. EN 61 010). (IEC 1010
resp. EN 61 010). It was developed and is manufactured
and tested in strict accordance with the quality assurance
standard ISO 9001.
Production QA is also certified according to guideline
94/9/EG.

2. Features / Benefits
● Designed for FSK communication, hand-held terminal connected
to separate terminals or test sockets. This facilitates operation in
conjunction with an "intelligent" 2-wire transmitter designed for
FSK and with a HART or user-specific protocol
● Electrically insulated between input circuit, output and power
supply / Fulfils IEC 1010 resp. EN 61 010
● AC/DC power supply / Universal
Available in type of protection "Intrinsically safe" [EEx ia] IIC
●
(see section "5. Data on explosion protection")
● Measurement / supply circuit monitored for open and short-circuits
/ Faults signalled by red LED, signalling relay and/or device failure
signal
● Output can be switched between 0...20 mA and 4...20 mA /
Universal matching to suit downstream device
● Green LED signals a power supply failure
