FAQ

Q: Can this module be used alongside P0914SD‑OB?
A: Yes, the OB variant offers additional I/O options but shares the same high-accuracy input architecture.

Q: Does it support both voltage and current inputs simultaneously?
A: Each channel must be configured for either voltage or current, but all 8 channels can be independently set for different input types.
