TopLab - Modular Design
Master and slaves
The TopLab series has 2 types of devices: masters and slaves. The master device contains the CPU unit and data storage capability. Salve devices serve as extensions to the master device. Each device can be equipped with 1 or 2 I/O modules.
The TopLab master is connected via standard cabling with a TCP/IP network. Salve devices are connected to the master via a CAN bus. Any number of master devices can be connected into a network. A maximum of 1000 I/O channels can be processed within a master-slave system.

Modular design
Each device (master or slave) can accommodate 2 different input/output modules. There are no restrictions in to which slots the modules are inserted. Sensors are connected via 4mm laboratory plugs.
Necessary steps for project planning:
- Create a list of analog and digital channels
- Allocate channels to modules
- Allocate modules to master and slave devices
Standard module measuring rate
Even with large numbers of channels the measuring rate is not affected by the number of input/output modules, with a maximum rate of 600Hz for standard modules. Each module is equipped with an A/D converter. A multiplexer consecutively connects each separate measurement channel.
Very precise measurement accuracy; resolution 24 bit; Autocalibration.
AMDT module features
- 8 channels for vibration and dynamic measuring
- ADFT for dynamic measuring in time domain signals
- AMDT/V for frequency and time domain signals. Simultaneous calculation of characteristic values.
