EL3051, EL3052, EL3151, EL3152 | 1-, 2-channel analog supply terminals 4…20 mA, single-ended, 12/16 bits

The job of the EL3051, EL3052, EL3151 and EL3152 analog input terminals is to supply power to measuring transducers located in the field and to transmit analog measurement signals with electrical isolation to the automation device. The voltage for the sensors is supplied to the terminals via the power contacts. The power contacts can optionally be supplied with operating voltage in the standard way or via a supply terminal (EL9xxx) with electrical isolation. The input electronics are independent of the supply voltage of the power contacts. The reference potential for the inputs is the 0 V power contact. The EtherCAT Terminals indicate their signal state by means of light emitting diodes. The error LEDs indicate an overload condition and a broken wire.
