2-channel pulse output module for ET 200SP

• Operating modes:
  • Single pulse with defined length
  • Pulse chain with defined number of pulses
  • Pulse width modulation (with flexible ON period, optional current control and dither function)
  • PWM signal for controlling a DC motor
  • ON and OFF delay; rising and falling edge can be delayed separately to the microsecond
  • Frequency output with defined output frequency
• Hardware:
  • 2 channels 24 V, 2 A output current
  • Parallel switching for enhanced performance on 4 A output current
  • Switching frequencies to 10 kHz; at reduced output current to 0.1 A up to 100 kHz
  • Push-pull output driver for especially steep edges at the outputs
  • Polarity change in DC motor operation for direction reversal
  • 1 high-speed 24 V digital input per channel with parameterizable input delay from 4 µs
• Channel functions:
  • HW enable;
    start of signal output with the onboard digital input
  • Parameterizable ON delay;
    for precise deceleration between the HW enable and the start of output
  • Current measurement in the operating modes pulse-width modulation and pulse chain;
    enables control of the output current mean value over a period. Temperature influences can thus be balanced to the resistance of the actuator.
  • Cyclic control of the respective main setpoint from the PLC in every operating mode;
    other values can be modified flexibly from the user program.
• Supported system functions:
  • Isochronous mode;
    enables precision-timed connection of the setpoint output to a higher-level controller
  • Firmware update
  • Identification data I&M
