Frequently Asked Questions (FAQ)

• What does "sink I/O" mean? The outputs sink current to ground (common negative), typical for many industrial devices.
• Can circuits be changed while operating? No, circuit configuration changes typically require power cycling.
• What is tri‑state mode? The circuit acts as a high-impedance input, useful for bus‑type applications.
