The NWTL-111 is a distributed-intelligence wireless control node designed to replace standard photocell modules on outdoor lighting fixtures. It connects to a 7-pin twist-lock receptacle compliant with NEMA standard C136.41 to provide ON/OFF and dimming control. The BULIT also connects to a Legrand Wireless Network Manager via a robust and scalable self-healing wireless IP network.
