BP16
Backplane for MAL Amplifiers
Measuring Amplifers and Sensors.
Get Connected.
Backplane for miniature amplifiers: Up to 16
measuring amplifiers, converters, or any other
function modules can be integrated in the
BP16. If installed close to the signal, it provides
for high interference resistance. Ideal for
remote signal conditioning of passive sensors.
Signal Conditioning in Miniature
Format.
In type of construction, the cost-effective MAL
modules are designed like a 24-pin DIL IC.
Measurement applications can therefore be
realized even in problematic locations. With
suitable measuring amplifiers, multiple wire
technique can be realized, too.
Optimally Supplied.
The BP16 is operated with 9-30V. The
integrated amplifiers are supplied by the
electrically isolated power supply. In addition,
5V (50mA) with galvanic isolation are provided
for sensor supply.
Functional diagram
Signal Connection.
D-Sub Standard.
Sensors or other voltage signals can
comfortably be connected at a 37-pin D-Sub
female.
Connection to the DAQ System.
The amplifier outputs are available at a 37-pin
D-Sub female connector. They are connected
to the input lines of a data acquisition system.
Combining the BP16 with a measuring card or
DAQ system from bmcm makes an extreme
compact measurement system.
External Device.
The BP16 is accommodated in a stable
aluminum housing ideal for mobile use.
Notches in the housing frames allow for fixing
the BP16 to a DAQ system (e.g. USB-AD14f)
providing for a stable measuring unit.
The Smaller Options.
You Have the Choice.
For all needing less channels: The backplane
for miniature amplifiers is also available as a
2-channel version with carrier for DIN rail
mounting (BP2) or integrated in a waterproof
IP65 housing (BP2-BOX).

Summary of Contents for bmcm BP16

  • Page 1 Sensors or other voltage signals can function modules can be integrated in the comfortably be connected at a 37-pin D-Sub BP16. If installed close to the signal, it provides female. for high interference resistance. Ideal for remote signal conditioning of passive sensors.
  • Page 2 (e.g. ZU-PW10W available as accessory. 2 Connections, Pin Assignments, and Components The available connections and different components of the BP16 are shown in the following figure of the board (view on top of the board (fitted with components), connectors on both sides). The measuring amplifier slots are consecutively numbered from channel 1 = 1 to channel 16 = 16.
  • Page 3 BP16 Power Supply (DC) The BP16 is operated with 9-30V via the 3-pin DIN plug at the back of the device. Analog Inputs The 16 analog inputs or sensors are connected at the 37-pin D-Sub IN female on the back of the BP16. To realize cold-...
  • Page 4 Pin Assignment of the Amplifier Slots Each channel of the backplane can be equipped with miniature amplifiers of the MAL series from bmcm (see chapter 4.1) or compatible measuring amplifiers of other manufacturers. That means that all inputs can be adjusted to the most different signals and sensors.
  • Page 5 BP16 2.5.1 Bypassing a Free Slot If slot x (x=1..16) is not equipped with a measuring amplifier, as the input is open or only voltages are to be measured, this socket has to be bypassed by closing jumpers Jx and Jxc. In this case, this input cannot be operated differentially.
  • Page 6 37-pin D-Sub IN connector of the BP16 (see chapter 2.5.2, exception: resistance measurement as 2-wire measurement). The 5V pin (pin 17) generated by the BP16 and electrically isolated from the measuring amplifiers can be used for sensor supply.
  • Page 7 The option ZU-TR from bmcm (see chapter 4.2) is a comfortable solution for cold-junction compensation. The D-Sub 37 male connector with integrated LM35DZ only has to be plugged on the D-Sub-37 IN female of the BP16.
  • Page 8 All accessible pins are electrostatic sensitive devices. Provide for an earthed conductive work place when installing. • The jumpers of the BP16 are very damageable and not too suitable for use in motion. In case of contact problems and in steady applications, we recommend soldering the jumpers if necessary.
