Small and cost-effective incremental encoders have become indispensable in many applications. Beckhoff responds to this strong demand with the comprehensive EL51xx EtherCAT Terminal series for evaluation of 5 V incremental encoders with RS422 and TTL signals. Thanks to four new high-performance compact I/Os, the evaluation of incremental signals in the controller can now be implemented in an even more space-saving and cost-effective manner.
In this 30-minute webinar Irina Koring, product manager in Beckhoff's I/O division, will present the four new EtherCAT Terminals, which log incremental signals with high frequencies up to 5 MHz and feature numerous parameterization options and integrated functions. The presentation will focus on the advantages of the new EtherCAT Terminals, the different performance classes and the much-reduced space requirement. The function of the products will be demonstrated by means of a practical example.

EL5102 | EtherCAT Terminal, 2-channel encoder interface, incremental, 5 V DC (DIFF RS422, TTL, open collector), 5 MHz
The EL5102 EtherCAT Terminal is an interface for the direct connection of two incremental encoders with differential signals (RS422) or single ended signals (TTL and open collector), parameterizable per channel. Input frequencies up to 5 MHz can be processed. Two additional 24 V digital inputs are available for storing, blocking and setting the counter status. It is also possible to set the counter to a predefined value or to lock the counter directly through the process data. The error message output of an encoder can be connected and evaluated via the status input. The 5 V, 12 V or 24 V supply of the encoder can be provided directly via the terminal connection points.
EL5112 | EtherCAT Terminal, 2-channel encoder interface, incremental, 5 V DC (DIFF RS422, TTL, open collector), 5 MHz, 2 x AB/1 x ABC
The EL5112 EtherCAT Terminal is an interface for the direct connection of two incremental encoders with A and B track or one encoder with A, B and C track. Encoders with differential signals (RS422) or single-ended signals (TTL and open collector) can be connected. Input frequencies up to 5 MHz can be processed. In 2-channel mode, one 24 V digital input per channel is available for storing, blocking and setting the counter status; in 1-channel operation, both inputs can be used. It is also possible to set the counter to a predefined value or to lock the counter directly through the process data. The 5 V, 12 V or 24 V supply of the encoder can be provided directly via the terminal connection points.
EL5122 | EtherCAT Terminal, 2-channel encoder interface, incremental, 5 V DC (TTL, open collector), 1 MHz
The EL5122 EtherCAT Terminal is an interface for the direct connection of two incremental encoders with A and B track. Encoders with single ended signals (TTL and open collector) can be connected. Due to internal pull-up resistors, no external circuitry is necessary for open collector evaluation. Per channel a 24 V digital input is available for storing, blocking and setting the counter status. It is also possible to set the counter to a predefined value or to lock the counter directly through the process data. The 5 V, 12 V or 24 V supply of the encoder can be provided directly via the terminal connection points.
EL5131 | EtherCAT Terminal, 1-channel encoder interface, incremental, 5 V DC, 5 MHz, with 2 x digital output 24 V DC
The EL5131 EtherCAT Terminal is an interface for the direct connection of incremental encoders with differential signals (RS422) or single-ended signals (TTL and open collector). Two parameterizable 24 V DC push-pull, tristate outputs are available, which are set after reaching a specified count, frequency or speed value. This allows the realization of a digital cam controller, which uses position or time cams and ensures a precise response time independent of the fieldbus cycle.
