SK106 : 1W 4-20mA Input And Output Remote Control Wireless Switch Module
- SK106 series is Industrial Level remote wireless analog(4～20mA) and wireless switch module, which includes SK106-TX and SK106-RX. SK106-TX provides four Digital signal input Interface & four current analog input Interface, SK106-RX provides four switch control interface & four current analog output interface. The parameters can be modified by PC software / UART command. DIP switch on the module can used to change operating frequency (maximum 16 group), operation mode,Group ID etc. Using this module, user can replace wired device with the wireless connection, which significantly reduce the cost and save much time.
- SK106 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
Note: Below parameters base on 12V power supply/ 25℃ testing environment.
