Designed to operate within the 24–48 V DC range, the EL2535 supports inductive loads such as valves, solenoids, and coils with high precision and reliability. Each channel delivers a ±1 A output, controlled by a 10-bit resolution PWM signal with a switching frequency of up to 30 kHz. The terminal’s push-pull output design supports bidirectional current flow and offers inherent protection features, including short-circuit and reverse polarity protection. Integrated digital inputs allow for direct feedback or control signals without requiring additional terminals. With electrical isolation between the field and EtherCAT levels and a compact IP20 housing, the EL2535 ensures safe, stable, and efficient operation in industrial control systems. Key Features: Dual PWM Channels: Two independently controlled PWM outputs for current-driven applications such as solenoid and valve actuation. Current-Controlled Operation: Maintains precise current regulation (±1 A per channel) for consistent actuator performance. High-Speed Modulation: 30 kHz PWM clock frequency provides smooth and rapid signal control suitable for dynamic processes. Wide Voltage Range: Operates within 24–48 V DC, ensuring compatibility with diverse power supply configurations. Integrated Digital Inputs: Includes two 24 V inputs for additional control or monitoring functionality within the same module. High Resolution and Accuracy: 10-bit resolution guarantees fine-grained modulation for precise output control. Electrical Isolation: 500 V isolation between the E-bus and field potential enhances operational safety and signal integrity. Short-Circuit and Reverse Protection: Built-in circuitry safeguards the terminal and connected devices from electrical faults. Compact Modular Design: Space-saving EtherCAT form factor allows seamless integration with other Beckhoff I/O terminals. Stable Industrial Performance: Robust construction and reliable power handling ensure dependable operation across 0–55°C environments. The EL2535 delivers the reliability and precision required for high-speed current-controlled PWM applications in modern EtherCAT-based automation systems.
