Frequently Asked Questions (FAQ)

• Should I choose a Sink (BBD025) or Source (BBD024) block?
  Choose a Sink block (BBD025) if your field devices are designed to receive current from the module. Choose a Source block if you need to supply current to the devices.
• What does TTL compatibility mean?
  It means the block can directly interface with low-voltage +5V digital logic circuits, common in older control systems and some sensor interfaces.
• How do I configure the 32 circuits?
  Use a Genius Hand-Held Monitor (HHM) connected to the dedicated port to set each circuit as an input or output and configure parameters.
• What is the purpose of the configurable input filter?
  It allows you to add a delay (1-100ms) to ignore electrical noise or contact bounce, ensuring stable and reliable input readings.
• What certifications does this block have?
  The IC660BBD025 is UL certified and meets other relevant industrial standards for safety and performance.
