Collect, process and storing of measurement data Data logger – MDL 8/3 The MDL 8/3 is optimized to collect data for environmental monitoring and measuring sites far from any infrastructure. Robust and reliable technology enables secure data storage and data transfer by radio, GSM or GPRS. The remote parameterization is executed by modem / GSM. A flexible management and support by an assistance-system enables an easy plug-in and parameterization of any type of sensor without any need of external wiring at the sensor interface. For each sensor the measurement- and storing interval can be defined. For special measurement requirement a conditional storing can be activated. The data logger includes a comprehensive alarm management via modem by phone call or SMS. The notification can also activate a relay output. The non-volatile storage of 2MB can save up to 600.000 measurement values. The data logger saves actual values, average, minimum, maximum, standard deviation, sum and intenseness. The standard serial interface is used for data transfer by modem (analogue, ISDN, GSM, GPRS) and parameterization (local / remote). The optional serial interfaces integrate sensors by RS232 / RS485 with adjustable protocol. Features • Easy integration of any sensor independent from pin assignment and power supply without need of external wiring • Sensor database assist for fast and easy set up and maintenance • Time- and interval management for each sensor with synchronous and/or conditional storing. • Very low power consumption • Alarm management via modem by call or SMS • Parameterization by modem (analogue, ISDN, GSM) or local (RS232) • Connect ability for data transmission by Modem, GSM • Option: Channel-Extension for max. 40 analogue inputs • Option: Online data transmission by TCP/IP via GPRS (DCM module) or Ethernet (WEB II – module) to FTP- or MDS-Server. 2 x serial interface to integrate sensors via RS232 / RS485 with adjustable protocol by user.
