Product Description:

Beckhoff’s EL2262 is a two-channel digital output terminal in the EL EtherCAT Terminals series. Installed on a DIN rail EtherCAT segment, it delivers sub-microsecond switching for motion latches, high-speed sorting gates, and other deterministic control tasks in industrial automation. Each channel supplies 24 V logic power to field devices while remaining synchronized with the distributed clocks that govern the bus.

The terminal supplies its outputs from a rated voltage of 24 V DC, and each channel can deliver up to 0.5 A. An internal current limiter caps transient current at 4 A for 150 µs to protect the semiconductor drivers. The turn-on or turn-off time is less than 1 µs, and the minimum commanded output period is 1 µs, so pulse-width patterns remain sharply formed. A maximum throughput of 1 Msample/s allows full-rate updates when oversampling is enabled, while bus coupling maintains overall system synchronization within less than 100 ns. The module supports resistive, inductive, and lamp loads. Channel-level snubbers handle stored energy and restrict breaking energy to less than 150 mJ. Its two digital outputs operate independently while sharing the same E-bus backplane. The terminal can control devices that require precisely timed output signals, including sorting gates, piezo actuators, and fast stepper motor enable lines.

On the process-data side, each EtherCAT cycle can carry 4 bytes of input diagnostic data and up to 504 bytes of output pattern data. This capacity supports an oversampling factor of 1000 when fieldbus timing operates at 1 kHz. The Beckhoff E-bus draws a typical 70 mA, helping limit heat generation inside an enclosure. All circuitry resides in a housing that is 12 mm wide and meets the IP20 protection class. The narrow housing mounts directly beside adjacent EtherCAT terminals, conserving space on the DIN rail. Integrated data and power contacts connect the assembly to neighboring terminals without separate wiring for distributed-clock synchronization.
