Power injector for the EtherCAT® measurement chain
EtherCAT® data acquisition devices can be easily distributed using a single cable for power, data, and synchronization. Each cable can span up to 100 meters between DAQ nodes.
Since every DAQ device in the EtherCAT® measurement chain consumes power and some power is lost due to the resistance of the cables we need to inject an additional power supply if the measurement chain consists of many data acquisition devices.
A power injector is used to inject additional power into the EtherCAT® measurement chain. It is inserted in the same EtherCAT® measurement chain as other EtherCAT® data acquisition devices. The power injector will inject and supply fresh power for all the DAQ nodes connected after it.
