Beckhoff ED3172 | EtherCAT Terminal, 2-channel analog input

The ED3172 analog input terminal is a universal 10 V/20 mA input module

in the 16-bit class for demanding, dynamic 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 inputs are differential; the current inputs are single-ended.

This means that one channel connection point in each case is connected

to the 24 V DC power contact 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 ED3172 has two individually configurable inputs and supports 2-wire

connections.

Special features:

• combined input terminal: 10 V/20 mA

• ±107% measuring range

• v10 ksps conversion rate per channel for dynamic automation tasks

The ED series EtherCAT Terminals have push-in connection technology

which makes wiring easy and tool-free.
