It can control analog-driven actuators, valves, and lighting systems with fine resolution and adjustable duty cycles. Each channel supports an independent frequency setting between 1 Hz and 125 kHz, offering great flexibility in timing control applications. With a 24 V DC nominal voltage and short-circuit-proof output stage, the EL2502 ensures durable and safe operation. Its electrical isolation of 500 V between field potential and the E-bus provides additional signal integrity and system safety. Configuration is conveniently handled via the TwinCAT System Manager software, making integration into EtherCAT automation networks straightforward and efficient. Key Features: Dual-Channel PWM Output: Two independently configurable PWM channels for flexible signal generation. High Frequency Range: Adjustable from 1 Hz to 125 kHz, suitable for a variety of control applications. Adjustable Duty Cycle: 0–100% mark/space ratio controlled by 16-bit input values for precision modulation. Short-Circuit Protection: Built-in safety against overload and short-circuit events on each output. Electrical Isolation: 500 V separation between field potential and E-bus ensures stable operation. Independent Channel Configuration: Each output channel can be set to a unique frequency and duty factor. Push-Pull Output Stage: Capable of driving ohmic, inductive, or lamp loads efficiently. Integrated LED Indicators: Channel LEDs reflect output state and duty cycle brightness for quick diagnostics. High Resolution Control: 9–15 bit resolution allows accurate analog-equivalent signal control. Reverse Polarity Protection: Safeguards against incorrect wiring or voltage reversal. Compact EtherCAT Design: Standard terminal format fits seamlessly into modular Beckhoff I/O systems. Software Integration: Fully supported by TwinCAT System Manager for configuration and parameter setting. Industrial Durability: Wide operating temperature range and compliance with EMC and vibration standards. Flexible Mounting: DIN-rail installation with pluggable wiring option for easy maintenance. Certified Quality: CE, UL, ATEX, and IECEx approvals ensure global usability and compliance. The EL2502 delivers the reliability and precision required for high-speed signal modulation, motor control, lighting systems, and industrial actuation tasks.
