Introduction
Fig.6: EL3621-00201-channel analog input terminal 4…20 mA, differential input, 24 bit
The EL3621-0020 analog input terminal with factory calibration certificate handles signals in the range between 4 and 20 mA. The voltage is digitised to a resolution of 24 bit and is transmitted, electrically isolated, to the higher-level automation device. The terminal has a differential input. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
