Optimized control of proportional valves with PWM
The EL2535-xxxx output terminals are specially designed for the precise control of single and double-coil proportional valves and proportional solenoid valves. They regulate the output current through pulse width modulation (PWM) of the supply voltage and 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 pulse width current 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
- max. output current 3.5 A per channel at 24–48 V DC nominal voltage
