Description

SK108U includes SK108U-TX and SK108U-RX. SK108U-TX is an industrial serial control transmitter, it works with SK108U-RX to build wireless switch control system. SK108U-TX is serial interface which can connect with PC and other serial devices. One SK108U-RX has 4 channels relay output. One SK108U-TX can control multiple SK108U-RX. The frequency of the SK108U-TX and SK108U-Rx can be set to avoid frequency interference.
In hardware SK108U-Tx is the same as our SV series module, which has different output power and different interface for option.
SK108U-Rx is same as SK108 in hardware but different firmware.
SK108U strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
