BMCM AMS42/84 5B amplifier system

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.

Fuse

The fusing of the AMS backplane is effected on the backplane (see chapter 3) with one reversible semiconductor fuse. In case of overload, it turns of. 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-pole pin connectors, leading the input signals connected at the cassette panel to the backplane. The assignment of the 7-pole female connector on the board is illustrated in the figure on the right-hand side.

Supplementary products for AMS42/84

5B modules (MA series)

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:

| Product | Description | | MA-UNI | universal amplifier with galvanic isolation for U, I, R, PT100, DMS, LVDT | | MA-UI | multi-range amplifier with galvanic isolation for U, I | | MA-U | voltage measuring amplifier with galvanic isolation, 50kHz bandwidth | | MA-FU | frequency/voltage converter with galvanic isolation | | MA-DFI | digital filter module with galvanic isolation, 60dB/oct. | | MA-FI | filter module with galvanic isolation, 30dB/oct. |

Plug-in cassettes (AMS-K series)

The amplifier system can be individually equipped with 8 (AMS42USB) 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:

| Product | Description | | AMS-K-BIN5 | cassette with panel and 5-pole Binder female connector (712 series) | | AMS-K-BLANK | blank panel | | AMS-K-BNC | cassette with front panel and BNC female connector | | AMS-K-CO5 | cassette with front panel and 5-pole terminal connector | | AMS-K-THK | cassette with front panel and thermocouple socket (type K) |

AMS-HANDLE, AMS-HANDLE2

For mobile use, the AMS42/84 can be equipped with a lateral, foldaway strap carrying handle (AMS-HANDLE) or with two stable metal handles at the housing frame (AMSHANDLE2).

AMS-EXT8

With the add-on option AMS-EXT8, 8 additional analog channels each are available for the AMS42/84 accessible at the back of the amplifier measurement system. The AMS42 can be extended to max. 16 channels, the AMS84 to max. 32. The analog outputs are accessible at a second D-Sub37 female with the same assignment as the D-Sub37 female of the AMS device (see chapter 2.3).

Important notes for using the 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.

Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly disposed according to the WEEE directive or can be returned to bmcm at your own expense.
