1.4 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.
Fig.1: BIC as data matrix code (DMC, code scheme ECC200)
The BIC will be introduced step by step across all product groups.
Depending on the product, it can be found in the following places:
• on the packaging unit
• directly on the product (if space suffices)
• on the packaging unit and the product
The BIC is machine-readable and contains information that can also be used by the customer for handling
and product management.
Each piece of information can be uniquely identified using the so-called data identifier
(ANSIMH10.8.2-2016). The data identifier is followed by a character string. Both together have a maximum
length according to the table below. If the information is shorter, spaces are added to it. The data under
positions 1 to 4 are always available.
The following information is contained:

Example
Further types of information and data identifiers are used by Beckhoff and serve internal processes.
Structure of the BIC
Example of composite information from item 1 to 4 and 6. The data identifiers are marked in red for better
display:
BTN
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. batch designations on IO components, previous serial number range for
safety products, etc.). The BTN will also be introduced step by step, so it may happen that the BTN is not yet
coded in the BIC.
NOTE
This information has been carefully prepared. However, the procedure described is constantly being further
developed. We reserve the right to revise and change procedures and documentation at any time and without prior notice. No claims for changes can be made from the information, illustrations and descriptions in
this information.

2.1 Introduction
KL3444: 4-channel analog input terminal 0 ... 20mA
Fig.2: KL3444
The EL3444 analog input terminal process signals in the range between 0 and 20mA. The current is
digitized to a resolution of 12bits, and is transmitted, in an electrically isolated form, to the higher-level
automation device.
In the KL3444 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. This
reference ground of the inputs is electrically isolated from the 0V power contact. The power contacts are
connected through.
Overload is detected and the terminal status is forwarded to the controller via the K-bus. The Run LEDs
indicate the data exchange with the Bus Coupler, while the Error LEDs indicate overload.

The EL3454 analog input terminal process signals in the range between 4 and 20mA. The current is

automation device.
In the KL3454 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. This
reference ground of the inputs is connected to the 0V power contact. The 24V power contact is connected
to the terminals, in order to enable the connection of 2-wire sensors without external supply. The power
contacts are connected through.
Overload is detected and the terminal status is forwarded to the controller via the K-bus. The Run LEDs
indicate the data exchange with the Bus Coupler, while the Error LEDs indicate overload.

The EL3448 analog input terminal process signals in the range between 0 and 20mA. The current is
digitized to a resolution of 12bits, and is transmitted, in an electrically isolated form, to the higher-level
automation device.
The KL3448 variant combines 8 channels in one housing and is particularly suitable for space-saving
installation in control cabinets. The use of single conductor connection technology enables the connection of
multi-channel sensor technology with minimum space requirements. In the KL3448, the power contacts of
