Frequently Asked Questions

• Q: What makes the 1756-OB16IEF a "fast" output module?
  A: It has an extremely fast response time of under 25 microseconds and supports PWM, making it suitable for high-speed control.
• Q: What is the benefit of per-point isolation?
  A> Individual isolation prevents faults on one channel from affecting others, increasing system reliability and simplifying troubleshooting.
• Q: What is CIP Sync, and do I need a special module for it?
  A: CIP Sync enables precise device synchronization over EtherNet/IP. This module is a slave device and requires a master clock (like a 1756-EN2T series module) on the network.
• Q: Can I use standard terminal blocks with this module?
  A: No, it requires specific RTBs: either the 1756-TBS6H or the 1756-TBCH due to its 36-pin connector.
• Q: What is your return policy?
  A> We offer a 30-day return policy for all unused items in their original, unopened packaging.
