RK118DC 16-Channel 433MHz RF Remote Control Switch

The RK118DC brings sixteen independently controlled relay channels into one 433MHz wireless control system. Its 18-button handheld transmitter gives operators a dedicated control for each channel plus All ON and All OFF, making it useful when several circuits need to be switched from one position.

Independent control for multi-circuit installations

Use the receiver to organize separate switched outputs for lighting groups, equipment functions, or other compatible control circuits. The learning-code pairing design supports straightforward transmitter setup. Confirm the required relay behavior, load rating, and wiring arrangement for your application before installation.
