1.4 Marking of ELX terminals

Name

An ELX terminal has a 15-digit technical designation, composed of

• family key

• type

• software variant

• revision

example family type software variant revision

ELX1052-0000-0001 ELX terminal 1052: two-channel digital input terminal

for NAMUR sensors, Ex i

ELX9560-0000-0001 ELX terminal 9560: power supply terminal 0000: basic type 0001

Notes

• The elements mentioned above result in the technical designation. ELX1052-0000-0001 is used in
the example below.

• Of these, ELX1052-0000 is the order identifier, commonly called just ELX1052 in the "-0000" revision.
“-0001” is the EtherCAT revision.

• The order identifier is made up of

- family key (ELX)

- type (1052)

- software version (-0000)

• The Revision -0001 shows the technical progress, such as the extension of features with regard to the
EtherCAT communication, and is managed by Beckhoff.
In principle, a device with a higher revision can replace a device with a lower revision, unless specified
otherwise, e.g. in the documentation.
Associated and synonymous with each revision there is usually a description (ESI, EtherCAT Slave
Information) in the form of an XML file, which is available for download from the Beckhoff website.
The revision has been applied to the terminals on the outside, see ELX1052 with date code

3218FMFM, BTN 10000100 and Ex marking.

• The hyphen is omitted in the labeling on the side of the terminal. Example:
Name: ELX1052-0000
Label: ELX1052

• The type, software version and revision are read as decimal numbers, even if they are technically
saved in hexadecimal.

0000

0000: basic type 0001

Identification numbers

ELX terminals have two different identification numbers:

• date code (batch number)

• Beckhoff Traceability Number, or BTN for short (as a serial number it clearly identifies each terminal)

Datecode

The date code is an eight-digit number given by Beckhoff and printed on the ELX terminal. The date code
indicates the build version in the delivery state and thus identifies an entire production batch, but does not
distinguish between the terminals in a batch.

Structure of the date code: WWYYFFHH
WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version

Example with date code: 02180100:
02 - week of production 02
18 - year of production 2018
01 - firmware version 01
00 - hardware version 00

ELX1052, ELX1054 and ELX10588 Version: 2.1.0

Beckhoff Traceability Number (BTN)

In addition, each ELX terminal has a unique Beckhoff Traceability Number (BTN).

Ex marking

The Ex marking can be found at the top left on the terminal:

II 3 (1) G Ex ec [ia Ga] IIC T4 Gc

2.5 Intended use

WARNING

Endangering the safety of persons and equipment!

The ELX components may only be used for the purposes described below!

CAUTION

Observe ATEX and IECEx!

The ELX components may only be used in accordance with the ATEX directive and the IECEx scheme!

The ELX terminals extend the field of application of the Beckhoff bus terminal system with functions for
integrating intrinsically safe field devices from hazardous areas. The intended field of application is data
acquisition and control tasks in discrete and process engineering automation, taking into account explosion
protection requirements.

The ELX terminals are protected by the type of protection "Increased safety" (Exe) according to
IEC60079-7 and must only be operated in hazardous areas of Zone2 or in non-hazardous areas.

The field interfaces of the ELX terminals achieve explosion protection through the type of protection "intrinsic
safety" (Exi) according to IEC60079-11. For this reason, only appropriately certified, intrinsically safe
devices may be connected to the ELX terminals. Observe the maximum permissible connection values for
voltages, currents and reactances. Any infringement can damage the ELX terminals and thus eliminate the
explosion protection.

The ELX terminals are open, electrical equipment for installation in lockable cabinets, enclosures or
operating rooms. Make sure that access to the equipment is only possible for authorized personnel.

CAUTION

Ensure traceability!

The buyer has to ensure the traceability of the device via the Beckhoff Traceability Number (BTN).

The bus coupler and bus terminals are attached to commercially available 35mm mounting rails (DIN rails
according to EN60715) by applying slight pressure:

1. First attach the fieldbus coupler to the mounting rail.

2. The bus terminals are now attached on the right-hand side of the fieldbus coupler. Join the compo­nents with tongue and groove and push the terminals against the mounting rail, until the lock clicks
onto the mounting rail.
If the terminals are clipped onto the mounting rail first and then pushed together without tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.

Fixing of mounting rails

The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the mounting rails with a height of 7.5mm under the terminals
and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).

Mounting and wiring

Disassembly

Fig.17: Disassembling of terminal

Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:

1. Pull the terminal by its orange-colored lugs approximately 1cm away from the mounting rail. In doing
so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of
the bus terminal block easily without excessive force.

2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved
housing surfaces and pull the terminal out of the bus terminal block.

Connections within a bus terminal block

The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by
joining the components:

• The six spring contacts of the E-Bus deal with the transfer of the data and the supply of the Bus
Terminal electronics.

• The power contacts deal with the supply for the field electronics and thus represent a supply rail within
the bus terminal block.
The power contacts of the ELX terminals are supplied by the ELX9560 power terminal. This interrupts
the power contacts and thus represents the beginning of a new supply rail.

Power Contacts

During the design of a bus terminal block, the pin assignment of the individual Bus Terminals must
be taken account of, since some types (e.g. analog Bus Terminals or digital 4-channel Bus Termi­nals) do not or not fully loop through the power contacts.

Terminals for standard wiring

Fig.20: Connecting a cable on a terminal point

Up to eight terminal points enable the connection of solid or finely stranded cables to the Bus Terminal. The
terminal points are implemented in spring force technology. Connect the cables as follows:

1. Open a terminal point by pushing a screwdriver straight against the stop into the square opening
above the terminal point. Do not turn the screwdriver or move it alternately (don't toggle).

2. The wire can now be inserted into the round terminal opening without any force.

3. The terminal point closes automatically when the pressure is released, holding the wire securely and
permanently.

Observe the requirements for connecting cables and cross sections according to IEC 60079-7 and IEC
60079-11. See the following tables for the suitable wire size width.

3.6.3 Proper line connection

Always connect only one wire per terminal point.

When using fine-wire conductors it is recommended to connect them with wire end sleeves in order to
establish a safe, conductive connection.

In addition, make sure that the pin assignment is correct to prevent damage to the ELX terminals and the
connected devices.

3.6.4 Shielding and potential separation

Shielding

Encoder, analog sensors and actors should always be connected with shielded, twisted paired
wires.

CAUTION

Observe installation requirements in areas of potentially explosive atmospheres!

During installation, observe the requirements for cables, shielding and earth potential equalization in areas
of potentially explosive atmospheres according to IEC60079-11, IEC60079-14 and IEC60079-25.

WARNING

Ensure potential separation of the 24V Ex busbar!

In any case, make sure that the galvanic isolation made by the ELX9560 between the 24V Ex busbar
(power contacts +24VEx and 0VEx) and other system potentials (if applicable also functional or protec­tive earths) is not removed.

2. UL certification according to UL508 with limited power consumption. The current consumed by the de­vice is limited to a max. possible current consumption of 4A. Devices with this kind of certification are
marked by this sign:

Almost all current EtherCAT products (as at 2010/05) are UL certified without restrictions.

Application

If terminals certified with restrictions are used, then the current consumption at 24VDC must be limited
accordingly by means of supply

• from an isolated source protected by a fuse of max. 4A (according to UL248) or

• from a voltage supply complying with NECclass2.
A voltage source complying with NECclass2 may not be connected in series or parallel with another
