Linetype Water Leak Sensor - A-LC1A

A-LC1A linetype water leak sensor can monitor the dual-core leakage sensor cable up to 500 meters . It can be use with the sensor cable , and also can be use with the other sensor probes . Once the sensor contacted the water , A-LC1A will produce sound and light alarm ,and drive relay .The A-LC1A linetype water leak sensor using modbus RTU protocol controller programming ,and monitoring system to facilitate integration .
A-LC1A either as stand-alone leak detection alarm can also be integrated with other network hosts collected using .
It can be used in the base stations ,warehouses ,libraries ,museums ,parking lots and industrial sites and other important places of real-time leak detection ,and more can be used for air-handling units ,chillers ,liquid containers ,pump tank and other equipment needed to monitor leakage .· Practical and reliable twisted pair serial RS-485 communication test ,as far
as communication distance up to 1200 meters ,the standard industrial modbus protocol.
·12V DC power supply , the distinction between positive and negative access.
·Sensor sensitivity adjustable.
·A variety of communication baud rate and set the module address software and communication baud rate ,without the use of switch .
·Relay output in the form NC coexist ,are free to choose .
·Good anti-static ,anti-surge technology to ensure reliable operation of the product.
·Convenient 35MM DIN rail mounting.
·Dimensions 55*115*36mm

Note To avoid damage to the A-LC1A,store the unit int it's packaging until ready to install.

Selecting the mountion position
Chosse a location where the module will be protected from the elements,temperature extremes or heavy vibration.The A-LC1A is designed to be snapped onto standard 35 mm DIN rail. Existing electrical or instrumentation cabinets with spare rail space make good mounting locations. It is also possible to install a small section of DIN rail directly on a wall or cabinet surface and monut the A-LC1A in any location as long as it does not create a tripping hazard or expose the A-LC1A to impact damage. The A-LC1A should be monuted within 1200m wire run from the control system host.Contact the factory for methods to increase the wire run distance beyond 1200m.

Importat The A-LLM1 is an electronic unit.Take the following precautions to avoid damage to electronic components:
·Handle with care and avoid mechanical shock and impact.
·Keep dry.
·Avoid exposure to static electricity by touching a nearby piece of grounded equipment or water pipe prior to handling the A-LLM1.
·Avoid contact with metal filings ,grease,pipe dope and other contaminants.
