Intelligent Hotel RCU-485 Host (18 channels)
Core functions
01
Multi-channel control
18 programmable relay outputs, each of which supports independent switch control and can flexibly adapt to various loads (lights, appliances, etc.).
02
Stable communication
RS-485 bus architecture, strong anti-interference, the farthest communication distance is up to 1200 meters, support multi-master network.
03
Intelligent linkage
It supports linkage with door locks, thermostats, sensors and other devices (such as automatic lighting when entering the door and turning off the air conditioner when no one is present).
04
Remote management
Real-time monitoring of room status, batch distribution of policies or remote maintenance through hotel management software (PMS).
05
Energy saving mode
Built-in scene logic (such as sleep mode to turn off unnecessary devices with one click) reduces energy consumption.

Special Notes
Due to excessive competition in the lighting market, most light strips have a surge current exceeding 100A during startup. To ensure reliable operation of the equipment, multiple light strips must not be connected to a single circuit. If a single light strip's startup surge exceeds 100A, an AC contactor or surge suppression module should be installed.
