The RJ-HUB is a multi-port RJ12 hub that can be used instead of using multiple RJ12 Y-splitters. It can be used to connect your Sensors and Devices to the main Croptiva controller. Croptiva's main controllers utilize "universal" RJ ports that can accept sensors AND devices. So a single RJ-HUB can be used to connect all sensors and device modules using a single cable connected to the SEN-1 or GUARD-1 controller. The RJ-HUB features 16 RJ12 ports & 6 hard-wired 4-pin terminal blocks. The 24vdc power supply will provide power to all of the Sensors and Devices connected to the RJ-HUB. The RJ-HUB is IP66 to protect all of the cable connections from moisture and corrosion.
