MDS-5/MDS-5 Com Data Loggers - Description
SEBA's newly designed MDS-5 multi-channel data logger is the successor of the well known and reliable data logger MDS. The
very compact MDS-5 logger stands out by its higher data storage capacity (480,000 values), improved data security and, in
particular, lower power consumption.
The MDS-5 is especially characterized by the following features:
different operational registration modes: time-, dynamic- or event-contolled
individual on/off control of attached sensors
comprehensive alarm management with GSM/GPRS-modem incl. SMS messaging
The main and central component of the MDS-5 data logger is the independent CPU-unit with a serial flash-memory. In total up
to 12 sensors (8 analogue, 2 digital and other inputs) can be connected to this logger via user-friendly terminals. By default an
undisturbed and quick communication and data transfer is conducted by the RS232 or an USB-interface. Optional a bluetoothinterface
or modem module can be supplied.
The CPU board of the MDS-5 controls a CPU bus which links several CPU boards to one single-master unit / multi-slave.
Therefore, as an example, the data logger and the alarm management system can be set up with separate tasks.
The MDS-5 Com includes already an integrated GSM/GPRS-modem for data transmission.
