EtherCAT measurement modules: accurate, fast, robust

Beckhoff has extended its measurement technology portfolio with a new high-speed, high-precision measurement device series. The high-performance EtherCAT measurement modules open up opportunities in terms of accuracy, precision of measured values, cycle times, synchronisation and long-term measurement accuracy – the level of which was to date only offered by cost-intensive, dedicated devices when used in automation. Beckhoff now offers a system-integrated measurement solution, without platform or system gaps, for existing PC- and EtherCAT-based control technology. The product portfolio now ranges from simple analog 12-bit terminals to high-precision, 24-bit condition monitoring modules with a sampling rate of 50 ksamples/s.

The new devices are designed for versatile application in industrial and testing environments. The available options include multi-function channels with numerous integrated measuring ranges (60 V to 20 mV, ±20 mA, full/half/quarter bridge strain gauge, IEPE, thermocouple, RTD) and also price-optimised versions with different numbers of channels. The main feature of the EtherCAT measurement modules is the superior quality of the acquired data values, which is achieved through a range of measures:
