Radio universal actuator with exchangeable antenna. Impulse switching relay with 1 changeover contact, potential-free 10A/250V AC, incandescent lamps 2000W, with DX technology. Bidirectional. Encrypted radio. Standby loss only 0.9 watts. If required, a radio antenna can be connected. Modular device for mounting on a mounting rail. Supply voltage 230V. The radio universal actuator combines the functions of a radio antenna module and an actuator as a 1-channel impulse switching relay with DX technology. If the supply voltage fails, the switching state is retained. When the supply voltage returns, it is switched off in a defined manner. 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 terminal (N) and L to 15 (L). This results in an additional standby loss of only 0.1 watts. This radio actuator can also be controlled locally with a 230V control button on the terminal. In addition, the N conductor must then also be connected to the terminal (N). A glow lamp current is not permitted. 230V control button: control current 0.4mA. Maximum parallel capacity (approx. length) of the control line 0.3 microfarads (1000m). Bidirectional radio and/or a repeater function can be switched on. With bidirectional radio, every change in status and incoming central control telegrams are confirmed with a radio telegram. This radio telegram can be taught into other actuators, the GFVS software and universal displays.
