BECKHOFF EL4732 2-channel analog output terminal

The EL4732 analog output terminal generates signals in the range from -10 to +10 V. The voltage is at a resolution of 16

Bit galvanically isolated transported to the process level. The output channels have a common ground potential. The

Outputs are sampled with an adjustable integer multiple (oversampling factor: n) of the bus cycle time

(n microcycles per bus cycle). For each microcycle, the EtherCAT Terminal receives one set of process data, one after the other

be issued. The time base of the terminal can be distributed with other EtherCAT devices with high precision

be synchronized. With this method, the temporal resolution of the analog output signals can be increased n times

Increase bus cycle time. In connection with the EL37xx (analog input terminal with oversampling) time equidistant

Reactions, e.g. B. possible when a threshold value is exceeded. The EL4732 can handle a maximum of 100,000 values ​​(100 kSamples / s)
