All-In-One Measurement System. Compact. DAQ via USB. The AMS42-USB, a complete solution: amplifier technology and data acquisition. A high-quality USB data acquisition system is already integrated. Available in a robust aluminum housing as a mobile tabletop unit with skid-proof, tip-up feet. 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-USB 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. Now the 5B module only has to be fixed on the cassette and be integrated in the AMS system. Clearly Safe. The galvanic isolation provided by the 5B modules guarantees interference-free operation and protects the DAQ system and the PC against high potentials. Analog. 16 Inputs. 2 Outputs. Signals are connected at 8 amplifier inputs with 16 bit resolution and 250kHz total sampling rate. Additional 8 analog inputs and 2 analog outputs are available directly and without amplification at a D-Sub 37 female. Digital. 4 Inputs. 4 Outputs. 1 Counter. Digital states are recorded or set at four digital inputs and outputs each. For pulse measurements, an additional isolated counter input is provided. Plug & Play with USB. The connection to the PC is realized via USB. The AMS42-USB provides all typical USB features (e.g. Plug&Play, Hot-Plug). Open for Everyone. Widely supported: The amplifier measurement system can be used under Windows® XP/7/8/10 as well as under Mac OS X, Free BSD, and Linux. The complete software for installation and programming of the AMS42-USB is included for free. The device is supported by NextView® 4, the software for data acquisition and analysis. ► www.bmcm.de bavarian measurement company munich

Assembly a) Equip the AMS42-USB with the plug-in cassettes (see chapter 6.2) 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 option AMS-EXT8 for the AMS42-USB (see chapter 6.4), the additional cassettes 9-16 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...

2 Connections / Assignments All available connectors and operating elements of the AMS42-USB are accessible on the right-hand side of the device front and back. 2.1 Switch The supply of the 5B modules of the AMS42-USB is turned on (press "1") and off (press "0") with the switch at the front. This is indicated by the green LED "ON AMPL". The DAQ unit is supplied by the PC. 2.2 LEDs The two LEDs on the front of the device indicate various states. As already mentioned, the LED "ON AMPL." is on, when the 5B modules are powered with 9-40 DC IN (switch on "1" position). The other LEDs show the...

2.5 Analog Channels 2.5.1 Measuring Amplifier Inputs Eight 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 (see chapter 6.2). Additional 8 amplifiers inputs can be added with the option AMS-EXT8 (see chapter 6.4) at the back of the device. 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...

The 5 V auxiliary voltage at pin 6 can be used e.g. for sensor supply. All connections are led to the 15-pin D-Sub female connector on the back of the device. The following table and figure show the pin assignment. With the option AMS-DIG4 (see...

3.2 Interfacing Examples for Digital Inputs The 3.9kQ pull-down resistor sets the input to low if no voltage is applied there. 3.2.1 Connecting an Optocoupler Optocouplers provide optimum protection at each input line. With them, it is possible to connect higher voltages and to protect the hardware from being destroyed. In this regard, please also see application examples of the optocoupler you use. O Optocoupler cards featuring 8 inputs are available at bmcm. 3.2.2 Connecting a Push-Button / Switch Please make sure to use a push-button with debounce protection, because otherwise several...

Serial resistors in the output lines limit the current and protect the hardware from being destroyed. 3.3.1 Connecting an LED Only so-called low-current LEDs can be used, because they already work with 1mA current. Please also observe the total current listed in the technical data (see chapter 8). 15-pol. D-Sub Buchse/ 15-pin DSub female Ausgang/ output 3.3.2 Connecting a Relay A connected relay is ideal to switch higher currents. Since the field coil of the relay requires a higher current than provided by the measurement system at one line, a transistor is connected ahead. O Relay cards...

4 AMS Backplane The AMS-backplane provides 8 slots for 5B modules and the AMS-K plug-in cassettes (see chapter 6.2) carrying the 5B modules. If the AMS42-USB is used with the optional add-on AMS-EXT8 (see chapter 6.4), eight slots each are available on the front and on the back of the device. 4.1 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 (see fig. above) must be closed. O In the case of electrically...
