Frequently Asked Questions

• Q: How many field devices can I connect to this module?
  A: The 140DAI55300 supports 32 discrete AC inputs, allowing connection to numerous switches, sensors, or contact closures in a single module slot.
• Q: How are the 32 channels organized?
  A: Channels are arranged in 4 groups of 8, with 1780V isolation between groups for electrical separation and fault containment.
• Q: What's the difference between this and the 16-channel version?
  A: This module doubles the channel count while maintaining similar electrical characteristics, offering better space efficiency for applications requiring many AC inputs.
• Q: Can I mix different voltages within the groups?
  A: All channels share the same 115V AC rating. For mixed voltage applications, consider using separate modules or external signal conditioning.
• Q: How are input statuses indicated?
  A: Each channel has a dedicated green LED, plus module-level bus and fault indicators for quick visual diagnostics during operation and troubleshooting.
