BP16 / BP16-PC
Carrier board (with housing) for measuring amplifiers of the MAL series

Features

16 DIL sockets for MAL amplifiers
37-pole Sub-D input socket
37-pole Sub-D output socket
BP16: in external metal housing
BP16-PC: for installation in the PC
The BP16/BP16-PC (BackPlane)
features slots for
... 16 measuring amplifiers ...
of the MAL series and of other
manufacturers.
The BP16 is a backplane for am-
plifiers with housing used as an
external
device,
whereas
BP16-PC can be integrated in a
PC and connected internally to a
PC measuring card.
The BP16 / BP16-PC provides all
included amplifiers with

Applications
• controlling of processes
• development
• signal conditioning
• sensor adjustment
... electrically isolated supply ... .
For sensor supply additionally
... 5V, 120mA ...
with electrical isolation are pro-
vided.
The measuring amplifier modules
the
needed for signal conditioning are
... very reasonable ...
standard amplifiers.
To achieve optimum measuring
results, please see for a good sha-
red potential of the signals to be
measured, as there is no electrical
isolation of the measuring amplifi-
ers.
The input signals are connected at
a 37-pole Sub-D socket. The out-
put signals of the individual meas-
uring amplifiers can also be rea-
ched at an additional 37-pole Sub-
D socket.
The measuring cards of BMC
Messsysteme GmbH have an in-
ternal connection for analog input
channels, so that measuring signals
with short lines can be lead di-
rectly from the BP16-PC to the
measuring system.
As the BP16-PC does not need
much space the complete elec-
tronic equipment for measuring
data acquisition can easily be in-
stalled in portable PCs.
If using the appropriate amplifiers
also multi-conductor technique can
be realized.

  • Page 2 (see chapter 3.1). The carrier board BP16-PC is installed in a PC next to a measuring card. Keep in mind to supply the carrier board with the appropriate measuring amplifiers at the respective channels first before connecting the analog output channels of the BP16-PC to the internal analog input channels of the bmcm measuring card using the enclosed cable (for assignment fig.

So the excita- tion connections of channel x-1 are lead out at the 37-pole Sub-D socket replacing the original connections of the fol- lowing even analog inputs (e.g.

  • Page 7 A semi-conductor sensor LM35DZ is used with an absolute accuracy of ±1C°. The sensor is supplied by the BP16 / BP16-PC with 5V and produces a reference voltage for all measuring channels proportional to the cold-junction.
  • Page 8 • All accessible pins are electrostatic devices. Workplace must be conductive during installation. • The jumpers of the BP16 / BP16-PC are very damageable and not too suitable for use in motion, in case of contact problems and in steady applications we recommend to solder the jumpers if necessary.
