Wengart Digital Timer CN101A 12V DC, Weekly Timer Programmable, Potential-Free Contact with Protective Cover, LCD Display, Time Relay for Motorhome, Solar, Garden Watering and DIY

• Precise weekly programming and flexible control: the digital timer allows up to 16 on/off processes per day or week. With a time range of 1 minute to 168 hours, it offers maximum flexibility for the automation of your electrical devices in the household or hobby area.
• Potential-free output for universal applications: thanks to the potential-free contact (dry contact), the relay can switch circuits independently of the own power supply. This makes it ideal for controlling boilers, garage doors or as a signal switch in complex DIY electronics projects.
• Optimised for 12 V DC and mobile applications: specially designed for use in motorhomes, boats and solar island systems. The low power consumption saves your battery, while the internal backup battery ensures that your programs remain stored even in the event of a power failure.
• Integrated protective cover against dust and misoperation: The transparent flip cover protects the LCD display and control buttons from dust, dirt, and accidental adjustment of schedules. Ideal for use in workshops, cellars or near agricultural facilities.
• Easy installation and intuitive operation: The compact design allows for space-saving installation. The clear display shows the current status in real time, and the manual override function allows you to turn the output on or off at any time at the touch of a button.

Wengart CN101A 12V DC: the versatile timer for self-sufficient systems. The Wengart CN101A is a reliable, digital weekly timer specially designed for low voltage applications. Whether you want to automate your garden watering, control the lighting in your camper, or build an automatic chicken flap, this time relay gives you the precision and safety you need. Benefits of potential-free contact: Unlike standard timers that loop the input voltage directly to the output, the Wengart CN101A has a potential-free changer contact. This means that you can easily switch a 230V consumer or a separate control contact with the 12V supply of the watch without the circuits mixing. This is a crucial advantage for professional electrical installations. Recommended usage scenarios Camping & Motorhome: Control LED outdoor lights or ventilation systems to save batteries. Solar isolated systems: Timed switching of loads in 12V photovoltaic systems. Agriculture: automation of feeding systems or lighting control in stables. Home & Garden: Operation of 12 V pumps for irrigation systems or pond technology. FAQs - Your Buying Guide 1. Does the watch keep the settings in the event of a power failure? Yes, the device has a built-in high-performance lithium battery. This saves the programming and time for a long time, even if the external 12V power supply is interrupted. 2. What does "Potential-Free Output" mean exactly? It means the outputs (pins 3, 4, 5) work like an isolated switch. No electricity flows out of the watch itself. You need to apply the voltage you want to switch separately to the contact. This prevents short circuits when controlling external devices. 3. Is the timer suitable for outdoor use? Thanks to the included protective cover, the front is protected against dust and splashes of water. However, for complete outdoor installation, we recommend mounting in an appropriate waterproof housing (IP65). 4. Can I turn the device on and off manually? Yes, via the "Manual" button, you can switch between "Auto" (Schedule), "On" (Continuous On) and "Off" (Continuous Off) at any time without deleting the programming. Technical specifications: Operating voltage: 12 V DC. Switching capacity: 16 A (ohmic load) / 8 A (inductive load). Power consumption: approx. 2w Time range: 1 minute to 168 hours. Memory slots: 16 programs per day/week
