EL307x, EL4x7x: The new generation of multi-functional analog terminals
A new generation of Beckhoff analog I/Os
The EL3072, EL3074, and EL3078 analog input terminals record 10 V / 20 mA standard signals with 16-bit resolution and up to 2000 measured values per second. Each channel can be parameterized individually via the controller/TwinCAT; signals in the range of -10…+10 V, 0…+10 V, -20…+20 mA, 0…+20 mA, and 4…+20 mA can be processed by each channel. In terms of electrics, the voltage and current signals must be connected to different terminal points. The voltage and current inputs are single-ended, which means that one connection point of each channel is already connected in the terminal to +24 V or GND and no longer needs to be wired separately. With a technical measuring range of ±107% of the nominal range, the terminals also support commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43.
