EL336x, EL336x-0100: EtherCAT Terminals for multi-channel measuring bridge detection with integrated power supply.
EtherCAT Terminals for the connection of load cells
The EL3361 analog input terminal enables the direct connection of a resistor bridge (strain gauge) or a load cell using a 4-wire or 6-wire connection technique. It processes the ratio of the bridge voltage UD to the supply voltage UREF and outputs the final load value as a process value based on the terminal settings. This enables precise recording of weights, torques, and vibrations with a sampling rate of 10,000 samples per second.
The integrated bridge supply is generated from the 24 V of the power contacts, with a choice between 5 V and 10 V DC in the configuration.
The terminal also has a digital input and a digital output. The digital input can be used for functions such as taring. The digital output can be switched on the basis of local evaluations in the terminal depending on the measured value of the resistance bridge.
