LVC-IV & LVC-S offer low-voltage wireless control for electric screens. The LVC-IV module is used to control a single 110V/220V motor through a variety of low-voltage control options. The control module includes: 3-screw terminal block for a low-voltage “dry” contact wall switch, IR receiver jack, built-in RF receiver, two (2) RJ25 ports for RS232/RS485, low-voltage relay port with cable, and user-serviceable 3.5 A fuse. The LVC-S switch features 3-button operation with up, stop, and down directional functions. Three screw terminals on the back of the switch connect to the LVC-IV using your own low-voltage cable.
