Beckhoff EL1252-0060 | EtherCAT Terminal, 2-channel digital input, 10 V DC, 1 µs, timestamp

The EL1252-0050 digital input terminal acquires the fast binary 5 V control

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

form, to the controller. The EtherCAT Terminal has two channels that indicate

their signal state via light emitting diodes. The signals are furnished with a

time stamp that identifies the time of the last edge change with a resolution

of 1 ns. With this XFC technology, signal characteristics can be traced exactly

in time and correlated with the distributed clocks system-wide. With this

technology, machine-wide parallel hardware wiring of digital inputs or encoder

signals for synchronization purposes is often no longer required.

The switching thresholds of the input circuit are based on the CMOS level:

Signal voltage "0" < 0.8 V, signal voltage "1" > 2.4 V. The 5 V supply voltage

can be generated by the EL9505 power supply terminal and fed into the power

contacts.

Special features:

• 5 V inputs

• suitable for particularly fast signals due to very low input delay

• synchronized operation through distributed clocks XFC technology possible

• support of XFC technology timestamp

The EL1202 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 contains two

channels whose signal state is indicated by LEDs.

The EL1202 can support the XFC Distributed Clocks technology, i.e. the

input data can be acquired synchronously with other data that are also

connected in a distributed manner to Distributed Clock terminals. 

The system-wide DC accuracy is << 1 μs. To this end the user has to

switch to terminal version EL1202-0100 (see documentation).

The EL1144 digital input terminal acquires the binary 12 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 four channels that

indicate their signal state via light emitting diodes. The 12 V supply voltage

can be generated with the EL9512 power supply terminal, and fed into the

power contacts.

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.
