Professional FAQ

• Q: What does “sinking input” mean for the 900G32-0101?
• A: Sinking inputs require the field device to supply positive voltage. The module switches the ground side. Works with NPN sensors and dry contacts.
• Q: Can I mix 12VDC and 24VDC sensors on the same module?
• A: Yes. The input range is 10-32VDC. All channels accept this range, but they share common groups. Ensure same group has same voltage reference.
• Q: What is the benefit of 2-group isolation?
• A: You can connect field devices with different ground potentials. Each group of 16 is isolated up to 30VDC, preventing ground loops.
• Purchase Guide: I need a digital input module for a Honeywell HC900 controller. Is this compatible?
• A: Yes. The 900G32-0101 is designed for Honeywell 900 series systems including HC900. Check backplane compatibility.
• Experience-based Q&A
  : Our sensors have long cable runs. Will voltage drop affect readings?
• A: The module’s ON threshold is 9.5V minimum. With 24V nominal, you have good margin. For very long runs, use larger wire gauge to minimize drop.
