❓ Expert FAQ – Selection & Experience

• Why choose F5-MD1616R over multiple smaller modules?
  • Answer: The F5-MD1616R saves DIN rail space and wiring time. One module gives 32 I/O points instead of using four 8‑point modules. Very cost‑effective.
• Can inputs and outputs use different voltage supplies?
  • Answer: Yes, inputs use 24V from field devices. Outputs use separate 24V supply (19.2‑28.8V). They are isolated from each other.
• What is the group current limit for outputs?
  • Answer: Each group of outputs shares 0.5A total. If you use multiple outputs in one group, their combined current must stay under 0.5A.
• How does self‑recovery after short circuit work?
  • Answer: Every 10ms the module checks if the short is gone. If yes, output turns back on automatically. No manual reset needed.
• Can I mix NPN and PNP sensors on inputs?
  • Answer: Yes, inputs are bipolar. They work with both NPN (sinking) and PNP (sourcing) sensors. Very flexible for different field devices.
• What is delivery time for F5-MD1616R?
  • Answer: We ship within 24 hours via FedEx, UPS, or DHL. Express delivery takes 3‑5 business days worldwide.
• Is the 12‑month warranty extendable?
  • Answer: Yes, contact sales@powergearx.com for extended warranty options beyond the standard 12 months.
