Frequently Asked Questions (FAQ)

• Q: What voltage does this DC output module use?
  A: The 1791-0B16 is designed for 24V DC systems, with a functional range from 10 to 30V DC.
• Q: Does this module require an external fuse?
  A: No. It has built-in internal fusing for protection, which simplifies your electrical panel design.
• Q: What is the switching speed of the outputs?
  A: Outputs have a fast response, with a maximum turn-on delay of 0.5 ms and a turn-off delay of 1.0 ms.
• Q: Is special wiring needed?
  A: Standard 14 AWG wire is recommended. A termination resistor is only needed if this is the last block on the RIO link.
• Q: What is your shipping policy?
  A: We ship worldwide using express couriers and support a 30-day return policy for your complete peace of mind.
