The EL3702 Beckhoff 2-channel analog input terminal. Therefore, handles signals in the range between -10 and +10 V. In other words, The voltage is digitized to a resolution of 16 bits and is transmitted, electrically isolated, to the controller. For instance, the signals are over-sampled with an adjustable. In other words, integer multiple (oversampling factor: n). In other words, of the bus cycle time (n microcycles per bus cycle). Moreover, for each microcycle. However, the EtherCAT. Therefore, the distributed clocks function enables several EL3702 devices to be synchronized in almost any configuration. The maximum sampling rate per channel is 100 ksamples/s (100,000 samples/s).
The EL3702 is a high-performance 2-channel analog input terminal from Beckhoff. Moreover, a leading manufacturer of industrial automation solutions. In conclusion, This product is designed to enable accurate and reliable measurement. Therefore, of analog signals in a wide range of industrial applications.
