Low-voltage wireless control for electric screens, the LVC-IV features infrared technology. The LVC-IV low-voltage control module provides single 110V/220V motor control through a variety of low-voltage 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 (IR) remote control transmitter features 3-button operation with up, stop, and down directional functions. The IR remote control transmitter does not need to be "learned" by the LVC-IV. Simply point and operate.
