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 or as a 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.
Clearly safe.
Most of the 5B modules feature galvanic isolation of the channels from each other 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 (USB, LAN) are also available. With the 8channel extension AMS-EXT8, the number of channels can optionally be increased to 16 (AMS42) or 32 (AMS84) at the maximum.
Installation
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-pole 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 AMS42/84 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.
Software installation and start-up procedure
a) Connect your PC data acquisition system to the 37-pole D-Sub female.
b) Attach an external power unit to the 3-pole DIN coupling for 9-40V power supply (use a supply cable with a cross sectional area >1mm (>1 ~mm^{2}) ) and turn on the AMS42/84 by pressing the switch to "1" (ON) (see chapter 2.1 and 2.2).
c) Signals are connected at the specific female connector of the respective AMS cassette panel.

Connections / Assignments
All available connectors and operating elements of the AMS42/84 are accessible on the right-hand side of the device front.
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.
Power supply "DC In"
The AMS device is supplied with power (9..40V) via the 3-pole DIN plug. A power supply unit ZU-PW70W (24V, 2.92A DC) is optionally available.
| Assignment | | n. c. | | ground (GND) | | 9-40V DC |
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-xxx cassettes. To connect a PC data acquisition system, these analog outputs are led out to the 37-pole D-Sub female.
| Pin | AssignmentAMS42 | AssignmentAMS84 | | 1..8 | Analog OUT 1..8 | Analog OUT 1..8 | | 9..16 | n. c. | Analog OUT 9..16 | | 17..19 | n. c. | n. c. | | 20..27 | analog ground (AGND) channel 1..8 | AGND channel 1..8 | | 28..35 | n. c. | AGND channel 9..16 | | 36..37 | n. c. | n. c. |
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.
AMS backplane
The AMS -backplane provides 8 slots for 5B modules and the AMS-K-xxx 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 (AMS42) or 16 (AMS84) slots each are available on the front and on the back of the device.
Ground-to-ground resistance
The ground-to-ground resistance is required when the output ground is not electrically connected with the power supply ground. If the jumper (see fig. above) on the analog backplane is closed, the output switches of the modules are switched through.
