The EL2535-xxxx output terminals control the output current through pulse width control of the supply voltage. They are electrically isolated from the E-bus. The current values (0 to maximum output current) are specified by the automation device through a 16-bit value. The output stages are protected against overload and short circuit. Each EtherCAT Terminal contains two channels whose signal state is indicated by LEDs. The light emitting diodes simplify local diagnosis by displaying typical load and wiring faults.

Special features:

• 2 PWM outputs with push-pull output stage
• Suitable for inductive loads > 1 mH
• ±100 mA max. output current per channel at 24 V DC rated voltage
