Product Overview
Brand and positioning: The AMS42/84 5B amplifier system, launched by BMCM Messsysteme GMBH, is a modular measurement amplifier designed for industrial measurement scenarios. Its core advantages lie in flexible configuration, channel isolation, and multi signal adaptation. It can be combined with BMCM's data acquisition (DAQ) cards/systems to form high-performance measurement solutions.
Version differentiation:
|Version | Form Design | Core Features | Number of Basic Channels | Size (W × H × D)|
|AMS42 | Portable, aluminum shell+anti slip foldable foot pad | Mobile use, suitable for desktop scenes | 8-way | 23.5 × 13.2 × 25.6cm|
|AMS84 | Fixed, 19 inch rack mount | Stationary deployment, integrated dual backplate | 16 channels | 48.3 × 13.2 × 25.6cm (including mounting bracket)|
Core Configuration and Components
Power supply and interface
Power supply specifications: Input 9-40V DC (± 5%), connected through a 3-pole DIN plug, optional accessory ZU-PW70W power supply (24V DC, 2.92A); The minimum power consumption is 3W, and the maximum is 20W (depending on the number of 5B modules installed).
Signal output interface: D-Sub37 female head, which leads the amplified analog signal to the DAQ system. The pin allocation is as follows:
|Pin Range | AMS42 Allocation | AMS84 Allocation|
|1-8 | Analog Output 1-8 | Analog Output 1-8|
|9-16 | Not used (n.c.) | Analog output 9-16|
|20-27 | Channel 1-8 Analog Ground (AGND) | Channel 1-8 Analog Ground (AGND)|
|28-35 | Unused (n.c.) | Channels 9-16 Analog Ground (AGND)|
|Other pins | Unused (n.c.) | Unused (n.c.)|
Modular core components
(1) 5B Measurement Module (MA Series): The core functional unit supports measurement and amplification of different signal types. Most modules have inter channel electrical isolation characteristics, and some provide sensor power supply. The output signal is ± 5V or 0-5V. The specific models are as follows:
|Module model | Function description | Key features|
|MA-UNI | Universal amplifier | Electrical isolation, compatible with U, I, R, PT100, DMS, LVDT signals|
|MA-UI | Multi range amplifier | Electrical isolation, adapted to U and I signals|
|MA-U | Voltage measurement amplifier | Electrical isolation, bandwidth 50kHz|
|MA-FU | Frequency/Voltage Converter | Electrical Isolation, Achieving Frequency Signal to Voltage Output|
|MA-DFI | Digital filtering module | Electrical isolation, attenuation slope of 60dB/octave band|
|MA-FI | Filtering module | Electrical isolation, attenuation slope 30dB/octave band|
(2) Plug in box body (AMS-K series): used to carry 5B modules, equipped with different types of connectors at the front end, suitable for various sensors/signal access. The specific models are as follows:
|Box model | Function description|
|AMS-K-BIN5 | 5-core binder female head (712 series)|
|AMS-K-BANK | Blank panel (blocking unused slots)|
|AMS-K-BNC | BNC Female Head|
|AMS-K-CO5 | 5-pin terminal connector|
|AMS-K-THK | K-type thermocouple socket|
(3) Expansion accessories:
Channel Expansion: AMS-EXT8, each device can expand up to 8 analog channels, AMS42 can expand up to 16 channels, AMS84 can expand up to 32 channels, and the expansion channels are output through the second D-Sub37 female head on the back (pin allocation is consistent with the main interface).
Portable accessories: AMS-ANDLE (single-sided folding handle), AMS-ANDLE2 (metal handles on both sides of the body).
Others: USB extension cable (ZUKA-USB), 3-pole DIN female head (ZU3DIN), etc.

Installation and usage specifications
Installation steps:
a) Assembly plug-in box body: Push the AMS-K series box body equipped with 5B module along the slot guide rail to ensure that the 7-pin connector is docked with the equipment backplane; Unused slots need to be sealed with AMS-K-LANK blank panels.
b) Expansion module installation (if using AMS-EXT8): Install the expansion box on the back of the device.
c) Power connection: Connect 9-40V DC power supply through a 3-pole DIN plug (cable cross-sectional area should be>1mm ²), press the switch to "1" (ON) to start, and the green "ON" LED indicator light will light up to indicate normal operation.
d) Docking with DAQ system: Connect to PC or BMCM DAQ system through D-Sub37 female connector.
e) Signal access: Connect the target signal (such as thermocouple, voltage signal, etc.) to the front connector of the plug-in box.
Important Instructions for Use:
Safety requirements: Only applicable to ultra-low voltage scenarios; CE certified isolated power supply must be used; Signal cables need to use shielded wires, with only one end of the shielding layer grounded; Avoid solvent based cleaning agents and only use non solvent cleaning agents for wiping.
Operation taboos: Before replacing the box, the power must be turned off; Not suitable for security related tasks; Unauthorized modifications will void the warranty.
Maintenance and disposal: The equipment is designed to be maintenance free, and calibration needs to be returned to the BMCM factory; When disposing, it must comply with the WEEE directive and cannot be mixed with household waste.
