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 EL3078 has eight individually parameterizable inputs.

Special features:

• combined input terminal: 10 V/20 mA

• ±107% measuring range

• 2 ksps conversion rate per channel for standard automation tasks
