Beckhoff EL4732 | EtherCAT Terminal, 2-channel analog output, voltage

The EL4732 analog output terminal generates signals in the range between

-10 V and +10 V. The voltage is supplied to the process level with a resolution

of 16 bits and is electrically isolated. The output channels have a common

ground potential. The outputs are oversampled with an adjustable, integer

multiple (oversampling factor: n) of the bus cycle frequency (n microcycles

per bus cycle).

For each bus cycle, the EtherCAT Terminal receives a process data block that

is output consecutively. The time base of the terminal can be synchronized

precisely with other EtherCAT devices via distributed clocks. This procedure

enables the temporal resolution of the analog output signals to be increased

to n times the bus cycle time. In conjunction with the EL37xx (analog input

terminal with oversampling), responses with equidistant time intervals, e.g.

in the event of a threshold value being exceeded, become possible.

The EL4732 device can output a maximum of 100.000 values (100 ksamples/s)

per channel and second.
