2 Housing type 506
Product description
1 Product description
1.1 Function and configuration
The housing type 506 is used for single
mounting of a signal conditioning instrument
for VBUS-sensors of series 500 (width 5 TE =
25,4 mm) and, additionally for VEGATRENN
547V Ex or 548V Ex separator also with 5 TEwidth.
The housing can be either screwed directly
to the mounting plate or mounted to a carrier
rail (35 x 15 acc. to EN 50 022).
The housing consists generally of three components:
- Socket with terminals
The connection terminals for the sensors
are located at the bottom and the ones for
the outputs and the power supply on top of
the socket. Therefore, the necessary separation between intrinsically safe and notintrinsically safe circuits in Ex-applications
is ensured. For carrier rail mounting an appropriate adapter is integrated in the socket.
- Upper part of the housing with guide rails
and ventilation slots. Sufficient ventilation is
also ensured when connecting several
housings in series. No external ventilation
necessary.
- The attached bag includes blue Ex-labels
and coded pins.
If you already have a power supply of
20 … 53 V AC or 20 … 72 V DC available,
you can use the housing without power supply unit.
If you only have other supply voltages available, use a housing with integrated power
supply unit.
The power supply unit is suitable for a voltage range of 90 … 250 V AC and DC and
can power the module units.
A later retrofitting of the housing with a power
supply unit is possible.
Note:
The housing type 506 is only designed for
series 500 instruments:
- VEGAMET 514V, 514VD, 515V
- VEGATRENN 547V Ex, 548V Ex
The power supply unit of the housing provides no galvanic isolation from the supply
voltage. Series 500 instruments realise the
galvanic isolation in the signal conditioning
instrument.
The module instruments of the new series
500
- VEGAMET…
- VEGATRENN…
are generally provided for a power supply of
20 … 53 V AC or 20 … 72 V DC.
