The EL1262-0050 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 sampled with a configurable, integer multiple

(oversampling factor: n) of the bus cycle frequency (n microcycles

per bus cycle). For each bus cycle, the EtherCAT Terminal generates

a process data block that is transferred collectively during the next

bus cycle. The timebase of the terminal can be synchronized precisely

with other EtherCAT devices via distributed clocks.

This XFC procedure enables the temporal resolution of the digital input

signals to be increased to n times the bus cycle time. 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

• multiple sampling of a process data through oversampling

The EL1262-0010 is a universal, high-performance oversampling terminal for

input and output signals. It contains two input and two output channels that

can all be operated simultaneously at up to 10 Mbit/s. It can thus resolve

binary states with up to 100 ns fineness. Electrically it can read and output

differential RS422 (full duplex), RS485 (half duplex) as well as 5 V single-ended.

Termination and bias are electronically switchable for serial operation.

This makes it suitable for the most demanding high-speed applications, e.g.

laser control or the emulation and read-along of serial protocols.

It thus extends the application range of the previous EL1262/EL2262 with

1 Mbit/s by a factor of 10.

The signals are sampled with a configurable, integer multiple (oversampling

factor: n) of the bus cycle frequency (n microcycles per bus cycle).

For each bus cycle, the EtherCAT Terminal generates a process data block

that is transferred collectively during the next bus cycle.

The 16-channel EL1259 digital EtherCAT Terminal combines the functions

of the EL1258 – eight multi-timestamp inputs – with those of the EL2258

– eight multi-timestamp outputs. The high channel density in conjunction

with time stamping of the signals enables fast, efficient processes through

optimized sensor and actuator control. The EL1259 is also synchronized

with other devices through the distributed clocks system, so that events in

the whole system can be measured with a uniform timebase.

The combination of DC-switched inputs and outputs within one terminal

can be used for local switching tasks.

Special features:

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

• combination of inputs and outputs in one terminal

• high channel density

• synchronized operation through distributed clocks XFC technology possible

• high performance thanks to XFC multi-timestamp feature

The EL1258 digital input terminal acquires the fast binary 24 V control

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

isolated form, to the controller. Each EtherCAT Terminal has eight channels

that indicate their signal state via light emitting diodes. In comparison

with the EL1252. the EL1258 offers not only a higher channel density,

but also a higher performance thanks to the XFC multi-timestamp function.

Whereas the EL1252 can accept one edge change with time stamp per bus

cycle, the EL1258 offers the possibility to register up to 32 events with time

stamps. The EL1258 is synchronized with other EtherCAT devices through

the distributed clocks system, so that events in the whole system can be

measured with a uniform timebase.

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.

The EL1252-0010 digital input terminal acquires the fast binary 24 V control

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

form, to the controller. The EtherCAT Terminal contains two channels whose

signal state is indicated by LEDs.

wiring of digital inputs or encoder signals for synchronization purposes is often

no longer required. In conjunction with the EL2252 EtherCAT Terminal

(digital output terminal with time stamp), the EL1252-0010 enables responses

with equidistant time intervals, largely independent of the bus cycle time.

Special features:

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

• synchronized operation through distributed clocks XFC technology possible

• support of XFC technology timestamp

• detection of fast edges with simultaneous filtering out of short interferences by

10 µs input filter (cf. EL1252: 1 µs)

The ELX1058 digital input terminal allows intrinsically safe NAMUR field

devices installed in hazardous zone 0/20 and 1/21 areas to be connected

directly and acquires their signals in accordance with IEC 60947-5-6.

The sensors are supplied with a voltage of 8.2 V and return a diagnosable

current signal. A wire break or short circuit can thus be detected in addition

to the switching state. The LEDs display the signal states and any error states.

In addition to switches, incremental encoders with a NAMUR interface can

also be connected. The configuration of the signal inputs for this can be set

via software. 8 digital inputs are pre-set as standard. By choosing the appropriate

configuration, up to 2 incremental encoders can be operated simultaneously

with 2 digital input channels. You can select whether a positive or negative

switching sensor is connected for each channel for the digital inputs. 

This allows NAMUR NCs and NOs to be integrated into the control system.

Potential-free contacts can also be connected.

EtherCAT Terminals from the ELX series must always be operated in conjunction

with the ELX9560 power supply terminal, which generates an electrically isolated

output voltage (24 V EX) from the input voltage (24 V DC) to supply the downstream

ELX terminals. If a repeat supply is required, an ELX9410 and an ELX9560 can

be combined so that further ELX terminals can be connected in series.

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 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.
