• Frequently Asked Questions

  • What is the difference between F5-MD1616R and transistor output modules?
    The F5-MD1616R uses relay outputs, which handle both AC and DC loads up to 2A. They provide isolation but have slower switching speeds than transistors.
  • Can I use this module with both NPN and PNP sensors?
    Yes, the inputs are bipolar and accept both sourcing (PNP) and sinking (NPN) sensors. This makes the F5-MD1616R very flexible.
  • What is the maximum switching frequency for relays?
    For mechanical relays, we recommend less than 1Hz for full electrical life. For higher frequencies, consider transistor output modules.
  • Does this module work with the Flexem FC5 CPU?
    Yes, it connects directly to any Flexem FC5 CPU via the expansion bus. The system automatically detects the module.
  • Do I need external fuses for outputs?
    We recommend external fuses or circuit breakers for each common group to protect against short circuits, as relays do not have built-in protection.
