The Ethernet analog input system MSX-E3021 has 16 analog differential inputs, 16-bit, voltage or current inputs. 4 channels can be acquired simultaneously with 100 kHz. The system was developed for long-term measurement in the harsh industrial environment and thus has an extended memory of 4 GB. It has a robust normed metal housing with the degree of protection IP 65 and an extended temperature range from -40°C to +85°C. The ARM®9 32-bit processor allows the calculation of the acquired values. The Development Mode allows to customise applications individually. Through synchro connection, several MSX-E systems can be cascaed and synchronised with one another in the µs range.
