Product Description

Cana Kit is a manufacturer of high quality Electronic Kits & Modules. They produce a vast range of educational electronic kits as well as professional modules which are suitable for all levels from beginners to electronic kits to seasoned kit builders. With over 20 years of experience in the field, they are one of leading manufacturers of high quality electronic kits worldwide. The range of kits we stock include all the electronic components you need to make the kit, PCB, components, connectors etc & a detailed set of instuctions to build the kit including solder methods, tools required & how to read & mount the components. Generally users will need a soldering iron, solder, pliers, wire cutters & a power source once the kit is made, DC power supply or batteries. Some kits may need other items screwdrivers etc. Image supplied shows completed built kit. The CK191M1 is a new version of Cana Kits popular CK191 cyclic timer with unlimited applications. It is adjustable from Approx. 0.5 second to 1 minute. The timer incorporates a relay which can handle loads of up to 3A / 110V AC (1.5A/220V AC) or 24V DC. The timer offers independent On & Off time adjustments through two PCB mounted variable resistors. New Improvements & Features This new version of the CK191 offers the following additional features as compared to our original design: 1. On & Off LED Indicators. 2. Professional Screw-on Terminals for relay output as well as an on-board DC jack for easy connection to a DC adapter. 3. Greatly enhanced Accuracy. The original design was a conventional timer based on the popular 555 timer integrated circuit. All 555 based timers suffer in accuracy due to the fact that the timing period is based on the voltage across an electrolytic capacitor. The new design is much more accurate as its based on counting the frequency of an oscillator. The design is based around two 4541 Programmable Timer Integrated Circuits which will send a signal to the relay circuit once it reaches a specific count of cycles generated by the oscillator. The oscillators frequency is varied by the variable resistor which results in different timing periods. * Please note kits do not include solder which can be bought separately QF 204320 or QF 169053 Quick Overview Supply voltage: 9V DC Adapter Timing adjustment: ON period from 0.5 second to 1 minute OFF period from 0.5 second to 1 minute
