The EL2502-0010 output terminal modulates the pulse width of a binary signal, and outputs it electrically isolated from the E-bus. The mark/space ratio is preset by a 16-bit value from the automation device. The output stage is protected against overload and short-circuit. The EtherCAT Terminal contains two channels whose signal state is indicated by LEDs. The LEDs are driven in time with the outputs, and show the duty factor by their brightness. The EL2502-0010 supports EtherCAT distributed clock timestamps in order to influence switching on, off and over of a PWM signal with microsecond precision.

Special features:

• PWM output with push-pull output stage
• Max. output current 0.5 A per channel
• Separate frequency adjustable for each channel
• Synchronized operation through distributed clocks XFC technology possible
• Support of XFC technology timestamp
