About this item

• FUNCTION & APPLICATION : grl8-02 water level controller liquid level relay, with 5ft detector sensor PLT, a wide operating voltage of AC/DC 24-240V (50-60Hz), and a rated current of 10A. Sensitivity 5-100k¥Ø, supports 1 electrode control (when the minimum liquid level is reached, the water supply equipment is turned on, or when the maximum water level is reached, the drainage equipment is turned on.), or 2 electrodes control (maximum and minimum water level monitoring and control). By connecting electric ball valves, water pumps and controllers, automatic water supply and drainage can be achieved in fish ponds, reservoirs, swimming pools, water tanks, etc.
• INDICATOR BUTTON : grl8 02 ac dc 24-240v adjustable level relay working status is indicated by LED indicator: Power indicator: green LED (always on means the input power is normal). PUMP knob: has UP (water supply) and DOWN (drainage) functions. Sensitivity knob: adjustable 5-100k¥Ø. Delay knob: adjustable 0.1s to 10s
• PUMP-UP function: UP-1ton, when the water level drops below the monitoring level, the water pump will be turned on after Tt time (adjustable from 0.1s to 10s) and will be turned off immediately after reaching the detection level; UP-1toff, when the water level drops to the monitoring level, the water pump will be turned on immediately and will be turned off after Tt time after reaching the normal detection level; UP-2£¨Cannot be used with Tt time knob£©, when the water level is lower than the min monitoring level, the water pump will be turned on immediately and will be turned off immediately after reaching the max monitoring level
• PUMP-DOWN function: DOWN-1ton, when the water level rises and is higher than the monitoring level, the water pump will be turned on for drainage after Tt time, and will be turned off immediately after reaching the normal detection water level; DOWN-1toff, indicating that when the water level rises and is higher than the monitoring level, the water pump will be turned on for drainage immediately, and will be turned off after Tt time after reaching the normal detection water level; DOWN-2, when the water level is higher than the max monitoring level, the water pump will be turned on for drainage immediately, and will be turned off immediately after reaching the min monitoring level
• COMPACT AND EASY TO INSTALL: grl8 01 liquid level control relay dimensions are dimensions: 90 x 18 x 64mm/3.5 x 0.7 x 2.5 inches, mounted on 35mm DIN rail, 3.88 ounces, easy to install, portable and compact, electrical components supporting this standard can be easily clipped on the rail, no screws required, maintenance is also very convenient
