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.

The products are available in different versions, depending on the required physical

layer and additional functions.

Physical layer:

• copper-based RJ45 connection

• copper-based M8 connection

• optical fiber connection for single- or multi-mode

POF (polymer optical fiber) connection

Additional functions:

• ID switches for variable topologies

• Hot Connect and Fast Hot Connect technology for changing topologies

• integrated digital and safe I/Os for compact and space-saving solutions

• Extended Distance connection for distances up to 300 m

• metal housing and additional diagnostics for high-precision analog measurement technology

The EtherCAT Couplers are the link between the EtherCAT protocol at fieldbus

level and the EtherCAT Terminals. Since communication in the EtherCAT system

is continuous through to the last terminal, the coupler only converts the physical

layer without changing the process data stream.

There is a selection of three different technologies:

• EtherCAT: ultra-fast communication standard

• EtherCAT P: combines communication and power in one cable

• EtherCAT G: speeds up to 10 Gbit/s

A distinction is made between a coupler, a junction and an extension.

The EtherCAT Coupler is the head station with which the terminal segment starts.

The junction can be placed anywhere in the EtherCAT segment and thus allows

the setup of a star topology. The extension is plugged into the end of the EtherCAT

terminal block and allows a setup with a line topology.

The BK1150 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the Bus Terminals. The coupler

converts the passing telegrams from Ethernet 100BASE-TX to the internal, fieldbus-independent terminal bus. A station consists of

a coupler and up to 64 Bus Terminals plus a bus end terminal. The process image of the EtherCAT system is assigned automatically.

Up to 255 Bus Terminals can be connected via the K-Bus extension.

Special features:

• Compact design

• Connection technology: 2 x RJ45 socket

• Connection lengths: up to 100 m

• connects the EtherCAT protocol with the Bus Terminals

The BK1150 works in the same way as the BK1120 and complements this series with its compact design. The coupler has two RJ45

sockets. The upper Ethernet interface is used to connect the coupler to the network; the lower socket serves for the optional

connection of further EtherCAT devices in the same segment. The system and field supply, each 24 V DC, is provided directly at the

coupler. The attached Bus Terminals are supplied with the current required for communication from the supplied system voltage.

The field supply is forwarded to the individual I/O components via the power contacts with up to 10 A. The Bus Terminals are

parameterized via ADS through the KS2000 software; a KS2000 connector is not required. Alternatively, the controller (PLC, IPC) can

configure the Bus Terminals via PLC function blocks.

In the EtherCAT network, the BK1150 coupler can be installed anywhere in the Ethernet signal transfer section (100BASE-TX)

except directly at the switch. The EK9000 and EK1000 couplers are suitable for use at the switch.

The TwinSAFE Compact Controller is programmed via the TwinCAT Safety Editor in the same way as other TwinSAFE components. A

TwinSAFE project is created and loaded over EtherCAT into the EK1960. The EK1960 supports the establishment of 128 TwinSAFE

connections. For flexible adaptation to different safety tasks, the TwinSAFE Compact Controller can be combined with the TwinSAFE

I/O components in IP20 and IP67 and the TwinSAFE Drive Option cards.

In addition to the Safety over EtherCAT protocol, the EK1960 also supports the TwinSAFE SC technology. This makes the safe

transfer of data from TwinSAFE SC terminals to the EK1960 TwinSAFE Compact Controller possible.

The EK1960 also supports the processing of analog signals (16/32 bit, signed and unsigned). These signals can be transferred to

the logic as standard, TwinSAFE SC or Safety over EtherCAT signals. Analog signals can thus be checked for plausibility within the

logic.

Certified function blocks such as ADD, SUB, MUL, DIV, and also more complex ones such as Counter, Limit or Compare are available

for the processing of analog signals.

The EK1960 TwinSAFE Compact Controller extends the range of applications of the TwinSAFE integrated safety solution. The core of

the safety controller corresponds to the functionality of the EL6910 dedicated safety controller. Thanks to the compact design of

the EK1960 with 20 safe digital inputs and 24 safe digital outputs (up to 2 A), it covers in particular the safety requirements of

compact machines. The EK1960 can be operated “stand-alone” or networked with other controllers via the EtherCAT connectors. If

the coupler is operated in an EtherCAT network, it can be extended by all EL/ES terminals like any EtherCAT coupler. As a stand

alone device, it cannot be extended by terminals.

Special features:

• analog value processing

• incremental download

• diagnostic history directly on the component

• up to 128 safe connections

• up to 128 TwinSAFE groups

• up to 40 users

• TwinSAFE SC support

• Stand-alone operation (without EtherCAT connection)

• 20 safe inputs

• 24 safe outputs

• 4 optional relay outputs

• Standard outputs can be activated with integrated AND connection with a safe output signal
