Camille Bauer SIRAX B 811 Quick Start Manual

Plug-in Module SIRAX B 811
Power Pack with Additional Functions
for intelligent and conventional
2-wire transmitters
Application
The power supply unit SIRAX 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 SIRAX B 811 are designed for FSK
munication. They are used in conjunction with "intelligent" 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 sig-
nals 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 regula-
tions concerning electromagnetic compatibility EMC and Safe
Isolation (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.
Features / Benefits
● Power pack plugs onto backplane (mechanically latched by fasteners),
all electrical connections made to the backplane and not to the
SIRAX B 811 / Thus no wiring when replacing devices
● Designed for FSK communication, hand-held terminal connected to
separate terminals. 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 Part 2
● AC/DC power supply / Universal
● Available in type of protection "Intrinsically safe" [EEx ia] IIC
(see "Table 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
