EJ2521-0224 - 1-channel pulse train output module 24 V DC

Marking of EtherCAT plug-in modules

 

Designation

A Beckhoff EtherCAT device has a 14-digit technical designation, made up as follows (e.g. EJ1008-0000-0017)

Order identifier
family key: EJ
product designation: The first digit of product designation is used for assignment to a product group (e.g. EJ2xxx = digital output module).
Version number: The four digit version number identifies different product variants.
Revision number:
It is incremented when changes are made to the product.

The Order identifier and the revision number are printed on the side of EtherCAT plug-in modules (s. following illustration (A and B).

Notes

The elements mentioned above result in the technical designation. EJ1008-0000-0017 is used in the example below.
EJ1008-0000 is the order identifier, in the case of “-0000” usually abbreviated to EJ1008.
The revision -0017 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 web site.
The product designation, version and revision are read as decimal numbers, even if they are technically saved in hexadecimal.
 
 

Serial number

The serial number for EtherCAT plug-in modules is usually the 8-digit number printed on the side of the module (see following illustration C). The serial number indicates the configuration in delivery state and therefore refers to a whole production batch, without distinguishing the individual modules of a batch.

Serial number
Example serial number: 08 15 08 16
KK - week of production (CW, calendar week)
08 - week of production: 08
YY - year of production
