Wireless universal actuator with replaceable antenna. Surge current relay with 1 potential-free changeover contact 10A/250V AC, incandescent lamps 2000W, with DX technology. Bidirectional. Encrypted radio. Stand-by loss of only 0.9 watt. If required, a radio antenna can be connected. Series installation device for mounting on mounting rail. Supply voltage 230V. The wireless universal actuator combines the functions of a wireless antenna module and an actuator as a 1-channel surge current relay with DX technology. If the supply voltage fails, the switching state is retained. With recurring supply voltage is switched off in a defined way. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. To do this, simply connect the N conductor to the clamp (N) and L to 15 (L). This results in an additional standby loss of only 0.1 watt. From production week 08/16 this radio actuator can also be controlled locally with a 230V control
