Mini Logger - Interface and Data Logging Module


Interface & Data Logging Module

Our multifunctional interface and data logging module features an onboard SDHC based data logger as well as 4 serial ports (2x RS232/ 422/ 485, 2 x RS232), USB (host and slave) and CAN2.0B interface.

The optional available daughter board provides additional sensors often required in standard applications (such as 3-axis accelerometer/ inclinometer. 2 axis gyroscope, compass, pressure sensor). It includes 6 digital and 2 analogue inputs as well as 4 optically isolated and 4 high power output switches.

Helpful additional functions are a precision time base, a switchable power supply for external sensors and many more.

Furthermore it is possible to stack multiple modules (master/ slave configuration), if our customers’ applications require any additional ports.
This module is primarily intended to be a flexible and powerful multiport data logging system controller solution in buoy based or ocean floor sensor systems. This system is feasible to be used as a standalone version one or a combination with any of our telemetry systems offered. Due to the extra low power consumption it is ideally suited to be used for long-term deployments.

Our flexible and extensive firmware allows economical and reliable customization. It enables our customers to handle applications now, which cannot be concluded by the current available standard firmware.
