Practical and reliable twisted pair serial RS-485 communication, with a long communication distance of up to 200 meters and standard industrial Modbus protocol
L adopts DC 12V power supply, convenient for user applications
Multiple communication baud rates are available, and module addresses and communication baud rates can be set through software without the need for switches.
The output form of the relay is normally open, normally closed, and shared, which can be freely selected
When the product detects water leakage, the alarm indicator light "ALM" flashes and sounds an alarm.
The "CLR" alarm button of the product is pressed to stop the sound alarm after the water leakage alarm is eliminated
Good anti-static and anti surge technology ensures reliable operation of the product
