WF96L adopts linear isolation transformer for supplys, nice performance processors inside, 8-bit MCU for local control, 32-bit MCU for WIFI part, strong interference-free ability, suitable for various industrial occasions, and can the controller is stable, reliable, and long lasting for continue working.Real-time synchronous feedback of remote output status and water level.It can run independently without WIFI, and realize the function of single-machine control of water level.The on-off of output can be controlled remotely or manually (when the set water level value is not reached).Support high-on and low-off to control drainage, or low-on and high-off to control water replenishment, or select a time-limited control mode.With remote upper-limit and lower-limit water level alarm APP push function.The Tuya APP can display the current water level, priming water level, stop water level, and upper-limit and lower-limit alarm water levels, time-limited operation time and etc..Two-way outputs, one for water level control and one for anti-dry-burn.Four control modes design, add water, pump water, time-limited adding water, time-limited pumping water.The main account can share the device with others, and the device can only be added to one main account.Name: Water Level ControllerInstallation ways: 35mm Din-Rail installVoltage: AC220V; Less than 2WWater level display: 0%, 25%, 50%, 75%, 100%Water level control ranges: 25%, 50%, 75%, 100%Time limit: 0-720minutes, needs to be set on cellphone APP, 5 minute settingsOne-way output delay time: 0-30sWorking temperature: -10Celsius to 50CelsiusWifi standard: Wifi 2.4GHz B/GItem size: 89 x 55 x 44mm / 3.50 x 2.17 x 1.73inColour:As shownMaterial:plasticPackage Contents:1 x Water Level Controller1 x CableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
