Radio blind and shutter actuator 1+1 NO 4A/250V AC, not potential-free, for a shade element motor 230V AC. Standby loss of only 0.6 watt. For panel mounting. 49x51mm, 20mm deep. The terminals are plug-in terminals for conductor cross-sections from 0.2mm² to 2.5mm². With the comfortable tip technology up to 32 wireless universal switches, wireless direction switch and wireless central control button can be taught in. Contact switching in the zero crossing. Bi-directional radio can be activated. Supply, switching and control voltage locally 230V. When the supply voltage fails, a defined shutdown is performed. In addition to the radio control input via an internal antenna, this radio actuator can also be controlled locally by a conventional control button that may be installed in front of it. Either separate local control inputs for up and down as direction switches, or these two inputs are bridged and controlled with a single button as universal switches. The change of direction is then
