Key Features & Capabilities

• Each of the 16 points is independently configurable as a digital input, tristate input, or sinking output.
• Designed for direct compatibility with 3-wire solid-state and electromechanical sensors.
• Comprehensive diagnostics monitor for short circuits, overload, no-load, open wire, overtemperature, and failed switches.
• Features include output pulse test, configurable power-up defaults, and last-state hold functionality.
• Integral components: Electronics Assembly (IC660EBD021) and Terminal Base Assembly (IC660TSD021).
• Front-panel LEDs (Unit OK, I/O Enabled) and per-circuit load indicators provide clear status.
• Functions as a single node on a Genius Bus network, supporting daisy-chain connections.

Frequently Asked Questions (FAQ)

• Q: What is the difference between a "Sink" and "Source" I/O block?
  A: A Sink block (like the IC660BBD021) connects the load to voltage positive and switches the negative/ground side. A Source block provides the positive voltage.
• Q: Can I use one block for both input and output signals?
  A: Yes. The main advantage of the IC660BBD021 is that each circuit can be software-configured individually as an input, output, or tristate input.
• Q: What diagnostics are available on this block?
  A: It features extensive diagnostics including open wire detection (for tristate inputs), short circuit, overload, no-load, overtemperature, and failed switch detection.
• Q: What assemblies are compatible with this block?
  A> It requires the specific Electronics Assembly IC660EBD021 and Terminal Base Assembly IC660TSD021.
• Q: What is your shipping and return policy?
  A: We ship in-stock IC660BBD021 blocks within 5 business days via major couriers. We offer a 30-day return policy for unused items in original packaging
