The Functional Devices RIB01SBDC is a reliable, pre-packaged solution for 120VAC applications requiring 20 Amp SPST control. Designed with a Type 1 housing for durability, this "Relay in a Box" features a Class 2 dry contact input, allowing technicians to activate the device with low-voltage signals from thermostats, occupancy sensors, or building automation controllers. The integrated override switch is an essential feature for on-site troubleshooting, enabling manual control to bypass logic during HVAC maintenance or system testing. With a continuous duty coil and LED status indicator, this relay provides clear visual feedback on the activation state, ensuring an efficient install in commercial energy management environments. The plenum-rated enclosure and 1/2" NPT nipple allow for direct mounting to electrical junctions, offering a clean, professional finish for industrial relay projects. Universal Input: Compatible with a wide range of dry contact signals, including solid-state switches and mechanical relays. Manual Override: Features a 3-position switch (Closed/Open/Auto) for immediate circuit testing without needing to trigger the controller. High Load Capacity: Rated for up to 20 Amp resistive loads at 277VAC and 1 HP at 120VAC, making it suitable for motor and lighting control. NEMA 1 Enclosure: Includes a pre-wired design with 16-inch leads to reduce field labor and ensure consistent wiring. Longevity: Engineered for a mechanical life of 10 million cycles under standard operating temperatures of -30 to 140°F. Common Questions How do you wire the RIB01SBDC for dry contact activation? Connect the White/Blue and White/Red Class 2 wires to your low-voltage control device. The internal 120VAC power source will self-power the coil when these contacts are closed. Can this relay be used for motor loads? Yes, it is rated for 1 HP at 120VAC and up to 2 HP at 277VAC, making it ideal for fan and pump applications. Is this device suitable for plenum spaces? Yes, the housing is UL-accepted for use in plenum air-handling spaces according to UL916 specifications.
