AMS42/84

5B Amplifier System

Amplifier Technology at its Best.

Compact or 19 Inch.

Get your amplifier technology wrapped up with

the AMS42/84. Available in a robust aluminum

housing as a mobile tabletop unit (AMS42) with

skid-proof, tip-up feet for 8 channels or as a

16-channel stationary version (AMS84) for 19''

rack systems.

Modular Concept.

Equip Individually. Be Flexible.

The AMS device is equipped with cassettes, on

which the required 5B measuring amplifiers are

mounted. The variety of available 5B modules

allows for the optimum adaptation of the

AMS42/84 to any special measuring task.

Choose Connector.

Mount 5B Amplifier. Done.

The available plug-in cassettes have different

connectors on the front panel. Depending on

the sensor or signal to be connected, the

suitable cassette can be chosen. The 5B

module only has to be fixed on the cassette

now and be integrated in the AMS system.

Clearly Safe.

Most of the 5B modules feature galvanic

isolation between the channels and from the

data acquisition and control system. This

perfectly protects the whole system against

high potentials and interferences.

Well Supplied.

The AMS42/84 is operated with 9-40V via an

external power supply.

Connection to the DAQ System.

The amplifier outputs are available at a D

Sub37 female connector. They are connected

to the input lines of a data acquisition system.

Combining the AMS42/84 with a measuring

card or DAQ system from bmcm makes a

powerful measurement system.

Accessories. Just Makes it Easier.

To individually equip the AMS devices, various

5B modules and plug-in cassettes as well as

other accessories (e.g. external power supply,

carrying handle, connection cable) are

provided.

Versions and Options.

Something for Everybody.

AMS42/84 versions with an integrated DAQ

system (USB, LAN) are also available. With the

8-channel extension AMS-EXT8. the number of

channels can optionally be increased to 16 in

the AMS42.

1 Installation

1.1 Assembly

a) Equip the AMS42/84 with the plug-in cassettes (see chapter 4.2) carrying the required 5B

modules.

b) Carefully push the cassette along the guide bars of the relevant slot until the 7-way pin

connector of the cassette and the pins of the 5B module are plugged into the corresponding

connectors on the AMS backplane.

c) If using the AMS42 with the option AMS-EXT8 (see chapter 4.4), the additional cassettes are

mounted on the back of the device.

d) For a tight installation, fix the front panel at both ends with screws to the housing. Bridge

unneeded slots by a blank panel (AMS-K-BLANK) to protect the device against outside

influences.

e) If the AMS84 is mounted to a 19'' rack system, the relevant input wiring should be prepared first

before attaching the device to the rack system with screws.

1.2 Software Installation and Start-up Procedure

a) Connect your PC data acquisition system to the 37-pin D-Sub female.

b) Attach an external power unit to the 3-pin DIN coupling for 9-40V power supply (use a supply

cable with a cross sectional area >1mm2) and turn on the AMS42/84 by pressing the switch to

"1" (ON) (see chapter 2.1 and 2.2).

c) Signals are attached at the specific connector of the respective AMS cassette panel.

• To change the cassettes, the power of the AMS device must be turned off!

• If the AMS system is operated standalone, additional grounding to enhance shielding is

recommended but not mandatory.

2 Connections / Assignments

All available connectors and operating elements of the

AMS42/84 are accessible on the right-hand side of the

device front.

2.1 Switch and LED

The AMS42/84 is turned on (press "1") and off (press "0")

with the switch.

The green LED "ON" indicates the operation of the device.

2.2 Power Supply "DC In"

The AMS device is supplied with power (9..40V) via the 3

pin DIN plug. A power supply unit ZU-PW40W (24V, 1.67A

DC) is optionally available.

2.3 Analog Channels

8 (AMS42) or 16 (AMS84) analog signals can be connected to the

amplifier inputs available at the respective connectors of the cassette

panels.

Their assignment is illustrated in the data sheet of the AMS-K cassettes.

To connect a PC data acquisition system, these analog outputs are led

out to the 37-pin D-Sub female.

Depending on the application, the shield of the analog input cables can be applied to ground or 0V. Be

sure to connect at one end of the cable only. Run the signal ground separately if possible. Lay input

cable separately if possible.

• The housing of the D-Sub37 female is connected to the AMS housing (and ground eventually).

• If the device features 16 channels (AMS84. AMS42 + AMS-EXT8), the ground of the first eight

channels is not electrically connected to the ground of the next eight channels.

3 AMS Backplane

The AMS-backplane provides 8 slots for 5B modules and the AMS-K plug-in cassettes (see chapter

4.2) carrying the 5B modules. Two backplanes are integrated in the AMS84.

If the optional add-on AMS-EXT8 (see chapter 4.4) is used, eight slots each are available on the front

and on the back of the AMS42.

3.1 Ground-to-Ground Resistance

Ideally, the output ground is not electrically connected with the power supply ground. If, however, a

connection to ground is necessary (e.g. to use the output switch in the 5B module), the 2-pin jumper
