The EL1804 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 four channels whose signal state is indicated by

LEDs. The power contacts are connected through. With the EL1804.

the reference ground for all inputs is the 0 V power contact.

Special features:

• input specification type 1/3

• no bouncing due to mechanical switches thanks to 3 ms input filter

• +24 V and 0 V sensor supply connections

• tool-free connection by direct plug-in technique for solid wire conductors

• increased packing density with 16 connection points in the housing of a

12 mm terminal block

The EL1512 EtherCAT Terminal is an up/down counter and transmits

the counter value in an electrically isolated form to the higher level

automation device. When used as a single-channel up/down counter

(32-bit), the pulse is set via the clock input; the counting direction is

specified via the U/D input. Furthermore, the input can also be used

as a gate input for triggering the counter. In 2 counter mode, two

separate counters are available (Clock and Clock1 inputs), which can

be parameterized as up or down counters.

The signal states of the inputs are indicated by light emitting diodes.

The EL1512 is particularly suitable for simple counting tasks such as

the connection of a flow meter.

Special features:

• suitable for simple counting tasks with counting frequencies up to 1 kHz,

e.g., the connection of a flow meter

• one up and down counter or two separate up or down counters

The EL1502 EtherCAT Terminal is an up/down counter and transmits the

counter value in an electrically isolated form to the higher level automation

device. When used as a single-channel up/down counter (32-bit), the pulse

is set via the clock input; the counting direction is specified via the U/D input.

Furthermore, the input can also be used as a gate input for triggering the

counter. In 2 counter mode, two separate counters are available (Clock and

Clock1 inputs), which can be parameterized as up or down counters.

The signal state of the inputs and outputs is indicated by light emitting diodes.

Both outputs are switched according to the counter state, so that they can

be used as fast control signals for field devices. The EL1502 device supports

the distributed clocks function.

This means the counter can be read at constant intervals (DC accuracy << 1 µs).

Special features:

• suitable for fast counting tasks with counting frequencies up to 100 kHz

• one up and down counter or two separate up or down counters

• synchronized operation through distributed clocks XFC technology possible

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.

• 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.

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:
