Frequently Asked Questions (FAQ)

• What does "sink I/O" mean?
  In a sinking module, the outputs provide a path to ground (DC-). The field device must be connected to the positive voltage source (DC+).
• Can I use one circuit as an input and another as an output?
  Yes! The key feature of the IC660BBD021 is that all 16 circuits are individually configurable as inputs or outputs.
• Do I need a separate power supply for the sensors?
  No. The block provides power to the connected circuits; field output devices supply the 24/48VDC source.
• How do I configure the module?
  Use a Genius Hand-Held Monitor (HHM) connected to the dedicated port on the block's front.
• What is a tristate input?
  It is an input mode that allows the detection of an open wire fault in addition to the ON/OFF state, requiring an external resistor.
