Beckhoff EL1098 | EtherCAT Terminal, 8-channel digital input, 24 V DC, 10 µs, ground switching

The EL1002 digital input terminal acquires the binary 24 V control signals

from the process level and transmits them, in an electrically isolated form,

to the higher-level automation unit. The EtherCAT Terminal has two channels

that indicate their signal state via light emitting diodes.The EK9160 Coupler

provides direct connectivity for EtherCAT I/Os to the Internet of Things (IoT)

without the need for a control program.

It converts the E-bus signal representation to different IoT communication

protocols and enables in this way the simple and standardized integration

of I/O data into cloud-based communication and data services. Neither a

controller nor prior programming is necessary. 

The I/O data transmission can be parameterized in a user-friendly configuration

dialog of the integrated web server providing access via any browser.

The required cloud services and security functions (authentication, encryption,

etc.) can also be conveniently configured using a browser. Following

parameterization, the coupler autonomously transmits the digital or analog

I/O values to the cloud service, including timestamp.The EK1914 EtherCAT

coupler combines the functionalities of the EK1100 EtherCAT coupler with

standard and safe digital I/Os. This results in a compact design that is especially

suitable for applications with a low number of I/Os.

The ELX1054 digital input terminal acquires signals from NAMUR field

devices according to EN 60947-5-6. The sensors are supplied with a

voltage of 8.2 V and return a diagnosable current signal. In this way,

a wire breakage or short-circuit can be detected in addition to the

switching state. The LEDs indicate signal or any error states, channel

by channel.

Using a DIP switch on the side, it is possible to select channel by channel

whether a positive switching or negative switching sensor is to be 

connected. Thus, no changes to the PLC are required for the connection

of both NAMUR break contacts or make contacts.

EtherCAT terminals of the ELX series must always be operated in

conjunction with the ELX9560 power supply terminal. This terminal

generates an electrically isolated output voltage (24 V EX) from the input

voltage (24 V DC) for supplying the subsequent ELX terminals.

If a new power supply is required, the combination of an ELX9410 and

an ELX9560 can be used so that further ELX terminals can be added.

The ELX terminal segment must be terminated with one ELX9012. two

ELX9410 or one EK1110. The use of two ELX9410 allows the use of EL

terminals behind ELX terminals. With the EK1110. the terminal segment

can be continued via an EtherCAT cable, for example to implement

cable redundancy.

The EK1914 has safety parameters to adapt the functionality specifically to the

respective safety-oriented requirements (e.g., 1 channel evaluation vs. 2-channel

evaluation of the inputs, testing of the individual channels).
