• SECURE # Rolling code key fob device offers better security and far more code combinations (more than 18 quintillion - 18 x 10^18 possibilities, nearly a trillion more than typical fixed code or so-called learning code ones) and built on new platform using higher RF sensitivity -111dBm superheterodyne module for better long range and more stable performance. Also 433Mhz frequency is less crowded than 315Mhz in USA.
• EASY & FLEXIBLE # Two independent relay channels can either work together (in latching) for polarity reversing or individually (in pulse / hold) to control different electronics, such as one channel for garage door controller unit, the other for entry lights. Easy programming & easy to use DIP switches working mode selection between pulse / momentary, hold / toggle and latching mode.
• ENCLOSURE # Designed to work both indoor and outdoor, default enclosure supplied protects the inner radio receiver circuit board safe from rain or other tough weather, while customer can also use chemical glue or epoxy adhesive to seal the wiring holes after setup, providing IP55 equivalent waterproof protection level. Mounting holes are provided for easy installation to walls etc using screws.
• INTERFACE # 3-Level efficient switching power supply system. Our 202U receiver board accepts 12 volts - 24 volts AC or DC wide supply voltage range (min. current rating is 110mA@12V DC). Each relay can switch up to 10A @14V DC or 10A @125V AC for resistive load (6A @14VDC for inductive load). Built-in small DC motor / solenoid polarity reversing control capability by using interlock latching mode and both relays.
• APPLICATIONS # Used in anti-theft alarm control panels, home automation systems, short and long range turn devices on / off wirelessly, lifts, boats, marine, winches, motor-driven curtain, roller blinds, overhead garage door & gate barriers, motorcycles, vehicles, cars, truck, industrial and agricultural electrical control such as water pumps & sprayer, electric door release locks, windows, manual switches extender, LED lighting lamp bulbs and strips, entrance and access control etc.

KIT-1 is a complete wireless kit, which includes 202U receiver and TX134 transmitter. Solidremote 202U is 2-Ch wireless receiver built with high stability, security and performance in mind. Typical use includes garage door opener standalone receiver, LED strip remote controller, hobby motor forward & reverse remote control and more. Other than DIY projects mentioned above, 202U receiver has also been shipped with lifts, HVAC devices, parking controllers and more by our business partners for many years. FOR BUSINESS BUYERS: 202U receiver is customizable for bulk orders, we also have more remote control options. Important Notice - Please Read Before Purchase # Using this product requires basic electronics knowledge, or experience with similar products before. Customer might need soldering skill and material for wiring in some circumstances. # Due to variety of wiring in real world applications, our simple, one page hard copy manual only covers general purpose wiring diagram, wiring assistance is provided free of charge on a case-by-case basis by support. # Many new features in V5 version, such as timed output, additional working modes etc. requires further settings which may seems complex, especially for first time users. We have video tutorials to guide you through the process. # Our hobby motor polarity reversing is for small DC motors current rating <5A, such as those usually seen in toys, also receiver should be set to interlock-latching mode. Polarity reversing requires additional wiring by customer, our relay only open and close circuit. # Recommended power input voltage is 9-30Vdc (polarity doesn't matter) or 9-24Vac. Measure real voltage for AC before set up - Important, to avoid damage! since sometimes a labelled 24Vac adapter can get you as high as 28-30Vac and damage our receiver. # Our receiver's relay capacity is up to 10A @14Vdc / 10A @120Vac for resistive load, up to 6A @14Vdc for inductive load (e.g. motors). Security Matters Using insecure fixed code or learning code is just like give keys to stranger, you never do it in real life - Why not try our KIT-1 and be safer? New in V5 Built-in timed relay output provides more possibilities, also we have 3 more working modes added in V5, including true latching. Security - Abundant Code Combinations for Daily Use Our rolling code system offers better security and far more code combinations than many other products at comparable price, which still uses 'ages old' fixed code or learning code due to much lower cost. For Where Security Matters While there is nothing wrong with fixed code or learning code in hobby projects, you may not want to use it in real life applications such as garage door opener, entry systems etc. where security matters. Abundant Code Combinations Our RF system has more than 18 quintillion (18 x 10^18) possible codes, nearly a trillion more than typical fixed code or learning code ones. How big is a trillion? Let's take sand for example, if learning code's code pool is the size of an average sand, then our transmitter's code pool is bigger than dozens of standard football playgrounds. YES indeed that huge difference. Performance - Carefully Designed and Manufactured Range is one of the most popular questions customers ask regarding wireless products, you need better range and more stable performance, we heard you. Increase Transmitter Power vs. Better Sensitivity Receiver Unlike many other products which improve range by simply increase transmit power (while it works, it is not the right way). Our transmitter is designed with standards conformance in mind, we achieved better range, done right, by using better sensitivity receiver instead. Better Superheteodyne RF Module Unlike many others who just source RF module from outside, we designed our own instead, because we know it is crucial to RF performance. Every SolidAdvantage module is carefully designed by engineer and quality checked using state-of-the-art Rohde & Schwarz RF instrument before final assembly. This is to make sure every RF receiver module actually achieve -111dBm sensitivity (lower value means better performance) and better stability in the long run. Design - Flexible & Built for Humans True Independent Relay Programming Two independent relay channels can either work together for polarity reverse applications or individually to control different electronics. e.g. one channel for garage door, the other for entry lights. 202U receiver's control logic is transmitter button to receiver channel mapping, so it is much more flexible than other products, especially when dealing with multiple channels or even multiple receivers at the same time. Standard 510 Transmitters Memory While other receivers only offer small memory for several remotes, we offer enough memory for hundreds of remotes, as free upgrade for all customers. DIP Switches No more jumpers. The human friendly, easy to use DIP switches provide straightforward relay working mode selection & settings possibility. Visual Feedback No more guessing. Both relays on board have LED indicators, so customer knows exactly which relay is currently turned on. SIG and PWR leds are also onboard for quick system status check. Optional +5V Expansion Port For activate external devices when SIG led is turned on, one typical use is buzzer. Maximum current rating is 150mA for V5 and later versions. Adaptive Power Input Thanks to onboard switching power supply system, 202U receiver accepts wide power input range 12-24V AC or DC that is available at many places. Limit Switches Other than remote control command, 202U receiver also accepts external limit switches signal (e.g. infrared beam or other sensor) for feedback control. Plug n' Play Antenna Port Use your own antenna to extend range? No problem! our brand new connector design makes antenna installation easier than ever. Read more
