  • Working Principle:
    • The CPU writes target pulse count and frequency to the module’s internal registers via the backplane bus. The module’s internal hardware generates the pulse train autonomously using a crystal oscillator. Each output transistor switches on/off to produce the pulse train. The CPU can update parameters in real-time without stopping the pulse output.
  • Installation Requirements:
    • Mount in VersaMax chassis
    • Connect external 24VDC pull-up supply to each output (if not using internal)
    • Use twisted-pair cable for pulse outputs to reduce EMI
    • Keep pulse cables away from AC power lines
  • Usage Precautions:
    • Do not connect outputs directly to AC loads — transistor outputs are DC only
    • Ensure external pull-up voltage does not exceed 30VDC
    • Do not exceed 100mA per channel — use external relays for higher loads
    • Add flyback diodes for inductive loads (solenoids, relays)
    • Do not hot-swap
