00 - hardware version 00 Beckhoff Identification Code (BIC) The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is based on the ANSI standard MH10.8.2-2016.
The following information is contained: Item Type of Explanation Data Number of digits Example information identifier incl. data identifier Beckhoff order Beckhoff order number 1P 1P072222 number Beckhoff Traceability Unique serial number, SBTNk4p562d7 Number (BTN) see note below Article description Beckhoff article 1KEL1809 description, e.g.

Example of composite information from item 1 to 4 and 6. The data identifiers are marked in red for better display: An important component of the BIC is the Beckhoff Traceability Number (BTN, item no. 2). The BTN is a unique serial number consisting of eight characters that will replace all other serial number systems at Beckhoff in the long term (e.g.

• Each assembly must be terminated at the right hand end with a KL9010 bus end terminal, to ensure the protection class and ESD protection. Fig. 5: Spring contacts of the Beckhoff I/O components Installation on mounting rails WARNING...
Mounting and wiring Assembly Fig. 6: Attaching on mounting rail 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.
Mounting and wiring Disassembly Fig. 7: 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.
Mounting and wiring Fig. 8: Power contact on left side NOTE Possible damage of the device Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g. disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230 V).
Mounting and wiring Standard wiring (ELxxxx / KLxxxx) Fig. 9: Standard wiring The terminals of ELxxxx and KLxxxx series have been tried and tested for years. They feature integrated screwless spring force technology for fast and simple assembly.

Commissioning Commissioning Remarks for usage of relay terminals Analyze operation conditions It is extremely important to observe the technical specifications if fault-free operation is to be guar- anteed. If relays are to be used in a control system the expected operating conditions must be analyzed with great care.
Commissioning For the -0010 variants applies: The relays internally of these terminals would be switched near to the zero voltage crossing of an AC supply. Hereby the lifetime of the outputs is no longer dependent by the absolute lifetime of the relay. The result of an exemplary long term test with the following boundary conditions represent that: •...

Commissioning Mains quality requirements If mains voltage as “detection” voltage is used: In the event of mains voltage faults, which jeopar- dize precise synchronization with the mains voltage zero crossing, suitable mains filters should be used. Temperature compensation of the terminal The terminal provides an automatic temperature compensation that allows a soft switching in a wide temperature range.
