Description Realize the liquid level control. When the container liquid level is too low, the low liquid level alarm signal from the low liquid level sensor is triggered to trigger the C350 controller to close the relay and start the water pump to add liquid level. When the liquid level reaches a certain height, the high liquid level sensor sends a signal to trigger C350 The controller cuts off the relay and automatically stops the water pump, so it works in a cycle. So as to realize the function of automatic control of the container liquid level and keep the container liquid level stable. Product Features 1. AC95~265V wide voltage power supply 2. Relay dry node output, suitable for multiple load control 3. The control is diversified, and the water pump can be controlled in manual or automatic mode. 4. The installation is simple and convenient. It can be installed with screws or electric box tracks.
