SK100 : Industrial One Way Wireless Switch Module
- SK100 series is industry level remote wireless switch modules, output power range from 100mW to 5W for optional. It provides a single way signal input and a single way control output interface, simple, reliable, and so on. Users can also be combined with a friendly PC interface to configure the modified module's working channel in a wireless way. Making multiple simultaneous communications will not interfere with each other and easy to use. With this module users can easily replace the original wired environment to wireless control, thereby greatly reducing the cost of manual wiring.
- SK100 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
