Product Description:
The EL2535-0002 is a two-channel PWM output EtherCAT Terminal produced by Beckhoff within the EL EtherCAT Terminals series. The unit converts bus commands into pulse-width-modulated push-pull signals so that decentralized controllers can drive solenoids, valves, or other 24 V DC actuators without additional interface hardware. In plant automation it minimizes DIN-rail usage, letting system designers expand output capacity while keeping wiring and diagnostic integration inside the standard EtherCAT topology.
The terminal operates from a nominal supply of 24 V DC; this matches typical control-cabinet power rails and lets the device deliver symmetrical output currents up to ±2 A per channel for inductive loads greater than 1 mH. Each output is modulated at 30 kHz, a switching rate selected to minimize audible noise while maintaining precise duty-cycle resolution. Internally, a 10-bit converter sets the duty-cycle value so the controller can issue 1,024 discrete pulse ratios, supporting smooth proportional actuation. The housing is rated IP20, indicating finger-safe touch protection when installed inside an enclosure, and reverse-voltage circuitry prevents damage if the 24 V supply is wired incorrectly.
Power to the outputs is routed through the supply contacts, which are rated for 10 A so adjacent terminals on the EtherCAT strand can be fed without extra cabling. The enclosure measures 12 x 100 x 68 mm, matching Beckhoff’s standard single-slot profile and conserving DIN-rail space in compact control cabinets. Two sensor channels are available as 2 x 24 V inputs, enabling immediate feedback from limit switches or fault relays linked to the driven actuator. In the process image the module contributes 48 I/O bits, organized as two 16-bit process data words plus separate control and status bytes, giving the PLC concise command and diagnostic access. Because distributed clocks are not provided, any time-critical synchronization is handled by the controller cycle time rather than hardware-based timestamping.
