Measurement technology simply integrated: With the analog EtherCAT Terminals.

The EP3356-0022 EtherCAT Box enables direct connection of a resistor bridge or load cell in a 4-wire connection technology. The ratio between the bridge voltage UD and the supply voltage UREF is determined simultaneously in the input circuit and the final load value is calculated as a process value on the basis of the settings in the EP3356-0022. With automatic self-calibration (can be deactivated), dynamic filters and distributed clock support, the EP3356-0022 with measuring cycles of 100 µs can be used for fast and precise monitoring of torque or vibration sensors.

All four M12 sockets are connected, so that parallel operation of several strain gauges is possible.
