Product Description:
Beckhoff is a globally recognized leader in industrial automation and control technology. The company is renowned for its pioneering role in PC based control systems. Their product portfolio includes Industrial PCs (IPCs), I/O and fieldbus components.
The EL2535 EtherCAT Terminal from the EL series is used for controlling proportional valves and solenoids. It is equipped with two PWM outputs and push pull output stages. Each channel supports an output current of ±1 A. It suits inductive loads above 1 mH. The terminal operates at a nominal voltage of 24 V DC with a tolerance range of – 15 % to + 20 %. Electrical isolation of 500 V is maintained between the E bus and the field potential. It supports a duty factor range of 0 to 100 % controlled through current regulation. The terminal provides protection against reverse voltage, short circuit and overload conditions. Short circuit current typically remains under 2 A. The PWM signal operates at a frequency of 30 kHz that enables precise current control. The resolution for current output is 10 bit while the bit width in the process image is split into 48 inputs/outputs including two 16 bit data paths and two 8 bit control/status indicators.
The EL2535 EtherCAT terminal design includes signal LEDs for local diagnostics and channel state visualization. The E-bus draws about 110 mA of current while power contacts typically draw 30 mA in addition to the connected load. The terminal includes two digital 24 V input features. It does not support distributed clocks. The unit is housed in a compact terminal casing made of polycarbonate. It measures 12 mm wide, 100 mm high and 68 mm deep and has a weight of approximately 50 grams.
Frequently Asked Questions about EL2535:
Q: Does the EL2535 EtherCAT Terminal support stable output control under high-frequency operations?
A: Yes, it uses a 30 kHz PWM signal for precise current control. This enables stable and accurate output even in demanding applications.
Q: How does the EL2535 ensure safety during reverse voltage or overload conditions?
A: It includes built-in protection for reverse voltage short circuit and overload. The short circuit current stays typically under 2 A for system integrity.
Q: Can the EL2535 EtherCAT Terminal reliably control inductive loads in automation environments?
A: Each output channel supports ±1 A current and suits loads above 1 mH. The terminal is optimized for proportional valve and solenoid control tasks.
Q: Is there signal feedback in the EL2535 to monitor channel status in real-time?
A: Yes, signal LEDs provide diagnostics and channel state visualization. This enables clear monitoring directly from the terminal during operation.
Q: How efficient is the EL2535 EtherCAT Terminal in terms of power usage and space?
A: The E-bus draws about 110 mA and power contacts take 30 mA plus load. Its polycarbonate body measures only 12 mm wide to save space.
