Introduction
The EPP3356-0022 EtherCAT P-Box enables the direct connection of a resistor bridge (strain gauge – SG) or a load cell using a 4-wire connection technique. The ratio of the bridge voltage UD to the supply voltage UREF is determined with high precision in the input circuit and the final load value is calculated as a process value on the basis of the settings in the EPP3356-0022. With automatic self-calibration (which can be deactivated), dynamic filters, support for Distributed Clocks and a sampling rate of up to 100 µs, the EPP3356-0022 is particularly suitable for the fast and precise acquisition of signals from torque or vibration sensors.
All four M12 sockets are occupied, so that the parallel use of several strain gauges is possible.
