EL3011, EL3012, EL3111, EL3112 | 1-, 2-channel analog input terminals 0…20 mA, differential input, 12/16 bits

The EL3011, EL3012, EL3111 and EL3112 analog input terminals process signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits (EL3011, EL3012) or 16 bits (EL311x), and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminals have differential inputs and possess a common, internal ground potential. The EL3011 and EL3111 are the single-channel versions and are characterised by its fine granularity and electrical isolation. The EL3012 and EL3112 versions combine two channels in one housing. Overload condition is detected, and the terminal status is relayed to the controller via the E-bus. The EtherCAT Terminals indicate their signal state by means of light emitting diodes. The error LEDs indicate an overload condition and a broken wire.
