Beckhoff ED3174 | EtherCAT Terminal, 4-channel analog input, multi-function

The ED3174 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 ED3174 has four individually configurable inputs and supports

2-wire connections.

Special features:

• combined input terminal: 10 V/20 mA

• ±107% measuring range

• 10 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.
