Frequently Asked Questions (FAQ)

• Q: Is the ABB 07-DI-93-I compatible with older CS31 systems?
  A: Yes, it uses the standard EIA RS-485 CS31 bus protocol and loops through seamlessly.
• Q: Can I connect both 2-wire and 3-wire sensors?
  A: Absolutely. Each input supports 2-pole and 3-pole switching contacts or initiators.
• Q: What is the maximum cable length for the CS31 bus?
  A: Refer to your system manual; typically up to 500 m with proper termination.
• Q: Does the module provide isolation between inputs and bus?
  A: Yes, the CS31 bus connection is electrically isolated from all other module components.
• Q: What does the red "Input Overload" LED mean?
  A: It indicates a short-circuit or overload on the sensor supply voltage – check your wiring.
• Q: Is the module hot-swappable?
  A: Not recommended. Power down the CS31 bus before connecting or disconnecting.
• Q: Do you have stock of the ABB 07-DI-93-I?
  A: Yes, we keep ample stock for immediate shipment.
