This item is an automatic tank DRAIN controller (not to be confused with the refill controller version). This board will watch the tank using 2 float switches and detect when it is high / full (using the upper float switch) and activate the relay so you can drain it e.g. activate a pump or solenoid valve (until the lower switch detects the tank is empty or very low). Unlike using a timer, latching relay or some other versions that may be available, this system uses an intelligent microcontroller operated board with integrated protection features and programming designed specifically to make decisions about how to manage the tank. The other advantage of this is that we can customise the programming to suit peoples needs (additional charge may apply). If you wanted this to send out a morse code SOS signal if a tank were to ‘overflow’ or a boat to start sinking…. it could also be used for a new type of toilet or giant ‘flush’ system that automatically manages and refills the cistern etc… this board is capable of doing it. It also has optically isolated inputs and has been in testing for well over a year to make sure it out-performs our expectations. This version does not have Ripple Correction Code(TM) as it does not need it for its usage scenarios.
FAQ Answers: YES You can use a push button instead of a float switch and yes you can order it with a different type of float switch e.g. stainless steel barrel switches.
FAQ Answers: Mounting – YES we can supply it with SELF-ADHESIVE STANDOFFS IF DESIRED (they click into each corner and you can literally stick the board inside an enclosure of your choice, preferably waterproof IP-rated!)
This kit consists of the board and 2 float switches as shown in the photos.
Datasheet, Instructions & Specification: IACS FK-X Series Datasheet
Program Guide and Information: FK-X Series Program Guide
|Board Input Voltage Options||Requires input voltage of between 9 and 14 volts (can be linked directly to a 12V Lead-acid or lithium battery or PSU).|
|Float Switch Power||The float switch will have the same as the board’s input voltage or lower put through it but only at a low amperage of around 5-25mA making it much safer than running for example mains voltage that close to water.|
|Switching Form||SPDT – NO, COM, NC|
|Switching Power (Amps)||Up to 30 amps continuous on Normally Open (30A) at 250V AC, OR 30V DC.|
25 amps on Normally Closed (NC).
|Switch Response Time (ms)||This board detects changes to the float switches immediately but may take a few seconds to decide whether to activate or change the state of the relay so responses may be between 0 and 5 seconds.|
|General Features||Input polarity protection, Flywheel, optically isolated float switch logic inputs for added protection, high quality, polarity LED and signal LED to indicate float state and power state. Only a very low voltage goes through the float switch – usually less than 5 volts DC. Mains voltage is always isolated from the float switch or sensor.|
|Compatible with||Self standing no add-ons required but you are free to custom wire it to whatever you like (check safety first).|
|Special Features||Intelligent program, this board essentially looks at and decides what to do depending on the float switch state, rather than just relying on timers and interrupts.|
|Suggested Uses||Alarm, lighting, security system, farm machinery, water butts, caravan and motorhome, backup tanks, sumps, fish tanks and aquariums, storm drains and watering sysytems, hydroponics.|
(L x W x H)
|7cm + screw terminal overhangs board by around +10mm so (8cm) x 5cm x 2.5cm.|
|PCB Type||Industrial Grade FR-4, does not flex or corrode|
|Surface Treatments||Lead-Free HASL (RoHS) or ‘ENIG’ for special batches, treated with a protective silicone based coating to resist / reduce moisture inhibition and/or corrosion|
|Place of Manufacture||ENGLAND (each and EVERY kit is quality tested on site)|
|Quality Control||CE, EMC, IEC 6100-6-1, 6100-6-3, RoHS, WEEE (Compliance Number WEE/FK 2902 UZ), IMS115|
|Safety Notices||Take care when working with high voltages, isolate before touching the unit, the board must be kept dry and should be mounted inside waterproof housing such as an IP rated enclosure with wires sealed.|
