Data logger with2x 4..20mA interface in rugged enclosure

This Data Logger records analogue values from two 4..20 mA current loop interfaces. The values are sampled at an adjustable rate and stored into a file on the memory card together with a time stamp. The data are stored in a text format – which is easy to import into Excel or other analysis programs. Long term data acquisitions are possible due to SD card support of up to 16 GBytes. The interfaces are galvanically isolated to separate power supply and interfaces.
