• What does DPDT mean in this relay?
  DPDT stands for Double Pole Double Throw. It means the relay can control two separate circuits and switch each between two outputs. This offers flexibility for complex control scenarios.
• How is the RIB01P different from other RIB models like RIB013P?
  The RIB01P uses a DPDT contact configuration, whereas the RIB013P is a 3PST-N/O relay. RIB01P is ideal for switching two circuits with a single input signal.
• Is this relay approved for plenum-rated installations?
  Yes, the RIB01P is UL-listed for use in plenum spaces and comes in a NEMA 1 enclosure.

• Tip: Use DPDT wiring diagrams to ensure each pole is wired correctly, especially in control applications requiring redundancy or interlock logic.
• Tip: Ensure control signal voltage matches the 120 VAC coil requirement before installation.
• Mistake to Avoid: Do not use with electronic ballasts or LED drivers — the relay is not rated for those load types.
• Mistake to Avoid: Don’t assume DPDT relays can substitute directly for SPDT or 3PST relays without redesigning the circuit logic.
