700MM-1000MM Heavy Duty Linear Actuator C One-Control-Eight Synchronous Control Kit (Model 0043108-2) WIFI Remote Control Switch 2) Press the button ▲This one control eight synchronous kit is used for heavy duty linear actuators to synchronize their operation. The kit includes eight Type C heavy duty linear actuators with built in Hall effect sensors, two four channel synchronous controllers (one master controller and one slave controller), one touch control handle, and a CH 3 remote control. Note: All linear actuators must be connected to the synchronous controller for the system to function
