• 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.
Foreword 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...
Fig. 4: ELX3252 - Two channel analog intput terminal for potentiometers, 16 Bit, Ex i The ELX3252 analog input terminal is suitable for operation in zone 2 and in not explosive areas. It allows the direct connection of potentiometers located in hazardous areas classified Zone 0/20 or 1/21. A stabilized power supply via power contacts of the ELX9560 power supply terminal and the ratiometric measurement of the input voltage offer the preconditions for precise measurement.
Product overview Technical data Technical data ELX3252-0000 Technology ratiometric potentiometer evaluation, potentiometer supply by the terminal Number of inputs Connection technology 3-wire Supply voltage for potentiometer max. 4.94 V Measuring range potentiometer 300 Ω … 40 kΩ Resolution 16 bit (incl. sign) Measuring error <...
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.
Special conditions of use for ELX terminals WARNING Observe the special conditions of use for the intended use of Beckhoff ELX terminals in potentially explosive areas (ATEX directive 2014/34/EU)! • The certified components are to be installed in a suitable housing that guarantees an ingress protection of at least IP54 in accordance with EN 60079-0 and EN 60529! The prescribed environmental conditions...

• The last terminal of each ELX segment is to be covered by an ELX9012 bus end cover, unless two ELX9410 power supply terminals are installed in direct succession for continuing the same terminal seg- ment with standard Beckhoff EtherCAT terminals (e.g. EL/ES/EK)! Examples for the arrangement of ELX terminals Fig. 5: Valid arrangement of the ELX terminals (right terminal block).

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). ELX3252 Version: 1.0.0...
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 Termi- nals) do not or not fully loop through the power contacts. Version: 1.0.0 ELX3252...
Ultrasonically "bonded" (ultrasonically welded) conductors Ultrasonically “bonded" conductors It is also possible to connect the Standard and High Density Terminals with ultrasonically "bonded" (ultrasonically welded) conductors. In this case, please note the tables concerning the wire-size width below! ELX3252 Version: 1.0.0...
Wire stripping length 8 ... 9 mm 8 ... 9 mm NOTE Maximum screwdriver width for ELX9560 Use a screwdriver with a maximum width of 2 mm to wire the ELX9560 power supply terminal. Wider screwdrivers can damage the terminal points. Version: 1.0.0 ELX3252...
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 protec- tive earths) is not removed. ELX3252 Version: 1.0.0...
