❓ Expert FAQ – Selection & Experience
- How do I choose between F5-MD0404N and F5-MD0404P?
- Answer: Choose F5-MD0404N if your loads connect to +24V (NPN sinking). Choose F5-MD0404P for loads connected to 0V (PNP sourcing). Inputs are identical.
- Can this module replace two separate input/output modules?
- Answer: Yes, F5-MD0404N combines 4 inputs and 4 outputs in one slim housing. Saves DIN rail space and wiring time.
- What happens if I short an output for a long time?
- Answer: The module limits current to 1.3A and tries to recover every 10ms. It will not be damaged, but the load won’t operate until the short is removed.
- Is the 12-month warranty extendable?
- Answer: Yes, contact sales@powergearx.com for extended warranty options. Standard is 12 months from invoice date.
- How fast can I get the module delivered?
- Answer: We ship via FedEx, UPS, or DHL express. Most orders arrive in 3-5 business days. Tracking is provided immediately.
