(see fig. above) must be closed.

In the case of electrically connected systems (e.g. PC), this jumper represents a high-resistance

bridge (1k ) and may generate a hum loop!

3.2 Module Pin Assignment

The pin assignment on the right shows the top view of the module

backplane (see chapter 3).

The pin assignment corresponds to the 5B modules of Analog

Devices®, BURR BROWN® etc. However, an additional 0EX pin has

been introduced, which is particularly suitable for ungrounded

shielding. This is a specific assignment of BMC Messsysteme

GmbH. The 0EX pin is not connected in modules of other

manufacturers.

3.3 Fuse

The fusing of the AMS backplane is effected on the backplane (see chapter 3) with one reversible

semi-conductor fuse. In case of overload, it turns off. To make the fuse work effectively again, first

remove the cause for overload before disconnecting the power supply of the AMS42/84.

3.4 Connection for AMS Cassettes

The cassettes are connected to the AMS backplane via 7-way pin connectors,

leading the input signals connected at the cassette panel to the backplane. The

assignment of the 7-way female connector on the board is illustrated in the figure on

the right-hand side.

4 Supplementary Products for AMS42/84

4.1 5B Modules (MA Line)

The 5B measuring amplifiers from bmcm allow for the professional

signal adjustment to a data acquisition system.

The amplifier output is 5V or 0..5V. Most of the modules are

electrically isolating and provide sensor supply.

The following 5B modules from bmcm are available:

4.2 Plug-in Cassettes (AMS-K Line)

The amplifier system can be individually equipped with 8

(AMS42-USB) or 16 (AMS84) plug-in cassettes.

Each cassette is equipped with the relevant 5B module and

suitable input connector.

The suitable input connector on the front panel guarantees for

the relevant connection to be available when exchanging the

cassette.

The following cassettes are available:

4.3 AMS-HANDLE2. AMS-FOOT

For mobile use, the AMS42/84 can be equipped with two stable

metal handles at the housing frame (AMS-HANDLE2).

If the AMS84 is not installed in a 19'' rack, a set of tip-up feet

(AMS-FOOT) can optionally be ordered.

4.4 AMS-EXT8

With the add-on option AMS-EXT8. 8 additional analog channels are

available at the back of the AMS42. In this case the device features max. 16

channels.

The analog outputs are accessible at a second D-Sub37 female with the

same assignment as the standard D-Sub37 female of the AMS device (see

chapter 2.3).

5 Important Notes for Using the AMS42/84

AMS42/84

• The device is only suitable for extra-low voltages - please observe the relevant regulations! For reasons

relating to EMC, it must only be used in closed PC housings.

• Only use an electrical isolated power supply unit (with CE).

• Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.

• For calibration purposes, the device must be returned to BMC Messsysteme GmbH.

• Use shielded cables for reasons relating to CE. Connect the shield to ground at one end only. Close open

inputs if possible.

• When mounting the cassettes, a connection between power supply ground and chassis of the device is made

via the module screw.

• The device must not be used for safety-relevant tasks. With the use of the product, the customer becomes

manufacturer 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.
