In a PL setup, which unit is commonly daisy chained with others?

• A. BP325 panels
• B. BP325 lines
• C. BP325 terminals
• D. BP325 units

Answer: (D)

Daisy chaining in a PL setup means linking multiple identical devices in a line so power or signals pass from one unit to the next through built‑in through ports. BP325 units are designed with that through-path, letting you connect one unit to another in sequence to scale the setup. Panels, lines, and terminals don’t typically provide that same through-connection path for chaining multiple devices, so they aren’t the ones commonly daisy chained. In short, BP325 units are the components built to be linked together in a chain to expand the system.
