Beckhoff Automation LLC EL3072 | EtherCAT Terminal, 2-channel analog input, multi-function, ±10 V, ±20 mA, 16 bit, single-ended, 2 ksps Preferred type

The EL3072, EL3074, and EL3078 analog input terminals are universal 10 V/20 mA input modules in the 16-bit class for simple control tasks. Input signals in the -10/0...+10 V or -20/0/+4...+20 mA ranges can be processed per channel. Voltage and current signals are connected to different terminal points. CoE can be used to set each channel to U or I mode in TwinCAT or from the controller. The voltage and current inputs are single-ended. This means that one connection point of each channel is connected to +24 V or 0 V (power contacts) in the terminal. All inputs are digitized with a 16-bit resolution and transmitted to the superordinate automation system under electrical isolation. With a technical measuring range of ±107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and evaluation in accordance with NAMUR NE43. The EL3072 has two individually parameterizable inputs and supports 2-, 3-, and 4-wire connection. It can supply sensors with +24 V directly. Special features: combined input terminal: 10 V/20 mA ±107% measuring range 2 ksps conversion rate per channel for standard automation tasks
