1.1 Models and Editions
The ML-x17 data logger is a small, ultra-low power, cost effective data logger with built-in 2G/3G/4G
cellular modem available for the EMEA, APAC and NA regions. This small data logger, is the same as
mlx-15, with the addition of an option port for expansion of possibilities.
The data logger can acquire physical signals by 2 current loop inputs, 3 voltage inputs (1 potentiometer
input) and 3 digital inputs. The data logger is provided with one serial port to capture measurements from
ASCII, MODBUS, NMEA or SDI-12 compatible sensors. External sensors can be powered by the data
logger itself, to prevent them to consume power while the data logger is a sleep. Up to 8 mathematical
channels are available to calculate meaningful engineering values derived from sensor input values (e.g.
a polynomial to calculate a flow from a stream level).

Example:
ML-417ADS-PV
is a data logger with built in global LTE-m/NB-IoT modem with PV-cover,
digital & analog inputs, a serial and accessory port.
The data logger will be supplied without pre-mounted cable glands, giving the user the freedom to choose
the number and size of the glands them self to avoid unnecessary points of risk for moisture penetration.
We recommend removing the PCB before drilling.
