The Beckhoff EL2502 EtherCAT Terminal provides 2 x 16-bit PWM outputs for precise control of ohmic, inductive, or lamp loads. Operating at 24 V DC, it delivers up to 0.5 A per channel, with built-in short-circuit protection and reverse voltage protection for safety. Each channel can be configured with a separate frequency via TwinCAT System Manager, offering flexibility in automation tasks. With a typical E-bus consumption of 140 mA and 30 mA from power contacts, the terminal is efficient and reliable. Electrical isolation of 500 V between the E-bus and field potential ensures robust safety. Compact in size (12 × 100 × 68 mm) and weighing 50 g, the EL2502 features a durable polycarbonate housing, IP20 protection, and integrated LEDs for status monitoring. Certified by CE, UL, ATEX, and IECEx, it complies with global standards for EMC, shock, and vibration resistance.
The EL2502 EtherCAT Terminal is ideal for applications requiring precise PWM signal generation, such as motor speed control, dimming of industrial lighting, or controlling valves and actuators. Engineers value its dual-channel design, which enables flexible control of different loads within the same system. Its compact DIN rail housing and simple spring-actuated wiring make installation quick and efficient, saving time in panel building. Maintenance teams benefit from the integrated status LEDs, which allow easy diagnostics during operation. With proven reliability and strong certifications, the EL2502 is trusted in diverse industries including packaging, robotics, material handling, and process automation. For students and trainees, it demonstrates how PWM output terminals enhance automation by combining accuracy, safety, and modular scalability in modern EtherCAT networks.
