AMS-K
AMS cassettes for 5B modules
Functional diagram
Modular amplifier technology.
The AMS amplifier systems from BMC Messsys-
teme GmbH can be equipped with different plug-
in cassettes of the AMS-K series - just so easy
and comfortable.
The right connection.
The available plug-in cassettes have different
connectors on the front panel. Depending on the
sensor or signal to be connected, the suitable cas-
sette can be chosen.
Equip individually.
The 5B modules are placed on the assigned posi-
tion of the cassette and screwed to the bracket.
Via the small bore holes at the relevant position
on the front panel, the potentiometers of the 5B
modules can still be reached for calibration even
after being mounted into the AMS device.
Plug-in. Screw tightly. Done.
The equipped individual cassettes are pushed
along guide bars into the AMS device, plugged
into the backplane with the front panel being
screwed tightly to the AMS housing. Unneeded
slots are covered by a blank panel.
It's all in the combination.
As the cassettes equipped with different 5B mod-
ules can be used in any combination, the AMS
amplifier system can perfectly be adapted to the
measuring task.
Versions and options.
Something for everybody.
AMS devices are available in two sizes: as a mo-
bile tabletop unit in 42HP format, or as a station-
ary 19'' rack system in 84HP format.
The 42HP version features eight slots for the
plug-in cassettes, the 84HP sixteen accordingly.
This number can optionally be increased
(AMS-EXT8) to 16 or 32 at the maximum.

2Assembly
Mounting of the 5B modules to the cassette and into the
AMS device is done in a few simple steps.
2.1 5B module
As the cassettes are already pre-assembled only mount
the relevant 5B module and fix it on the cassette using
the screw of the 5B module and the included flat nut.
2.2 Mounting in the AMS amplifier system
Insert the cassette board along the guide bars of the rele-
vant slot into the AMS housing in upright position until
the pins of the 5B module and the 7-pole pin connector
(P1) are plugged in the corresponding connectors of the
AMS carrier board. Now press the cassette with the right
touch in the backplane the front panel touching the
housing frame.
The cassette is screwed to the housing at both ends of
the front panel for a save installation. To better distin-
guish the input signals from each other, the inscription
fields on the panels can be used.
Mounting of the cassette must only be done with slight pressure to connect the pin plug with the car-
rier board! If the resistance is too high, check if the cassette is in the guide bar or if the pins are bent.
Too much pressure may damage the 5B module, the cassette, or the AMS device!

3Connections and pin assignments
The following figure shows a PCB of the AMS cassette.
The different types only vary by the female connector on the
front panel.
The input signal connected to the panel is internally available
at the 7-pole pin connector (P1) and is led to the amplifier via
the AMS backplane.
3.1 AMS-K-CO5
The 5-pole terminal connector of the standard cassette AMS-K-CO5 is hard-wired.
The pin assignment of the terminal connector (P4) and the internally connected 7-pole pin plug (P1) are
listed in the following table and figure:

To comfortably connect signals to the terminals, a package of eight 5-pole screw-type terminal blocks
(ZU5ST) are available.
3.2 AMS-K-BNC
The AMS-K-BNC cassette provided with a BNC female. In this case, only the connections
"HI" and "LO" are available for using 2-pole sensors.
3.3 AMS-K-BIN5
The connector of the AMS-K-BIN5 cassette is a 5-pole Binder socket of the 712 series.

3.4 AMS-K-THK
The AMS-K-THK cassette can be used for temperature measurements with thermocouple
(type K).
3.5 AMS-K-BLANK
To protect the AMS system against external influences, unused slots can be covered with
the AMS-K-BLANK, a blank panel without a connector.
4Slots for thermocouples or current shunts
If the cassette is equipped with a thermocouple amplifier, the cold junction compensation element delivered
with the module must be installed on the cassette (J2). If the cassette is equipped with a current amplifier, the
shunt delivered with the module must be installed on the cassette (J1). The positions of the slots J1 and J2 are
illustrated in Figure 1.
5B modules from bmcm do not need any extra equipping. These options have been implemented in the mod-
ules already.
5Important notes for using the AMS-K
•The AMS-K cassettes are only suitable for extra-low voltages - please observe the relevant regulations!
•Only use an electrical isolated power supply unit (with CE).
•All accessible pins are electrostatic devices. Workplace must be conductive during installation.
•Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
•The product must not be used for safety-relevant tasks. With the use of the product, the customer becomes manu-
facturer by law and is therefore fully responsible for the proper installation and use of the product. In the case of
improper use and/or unauthorized interference, our warranty ceases and any warranty claim is excluded.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly dis-
posed according to the WEEE directive or can be returned to bmcm at your own expense.
