Page 8: Marking Of Elx Terminals
• 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. -

Page 12: Product Overview
Fig. 4: ELX2792 - 2-channel relay output terminal, solid state, potential-free, Ex i The ELX2792 output terminal has two solid state relays, each of which is a changeover contact. Intrinsically safe loads can thus be switched up to zone 0/20. These could be ohmic loads, solenoid valves, contactors or optical/acoustic signal devices. -

Page 14: Intended Use
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. -
Page 15: Mounting And Wiring
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!

Page 17: Arrangement Of Elx Terminals Within A Bus Terminal Block
• 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 segment 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). -
