Eltako 1 potential-free switch 10A/250V AC, suitable for incandescent lamps up to 2000 watts, with a delay on release and a pre-warning for switching off, as well as a permanent light function that can be activated. Encrypted radio, bidirectional radio, and repeater function can be enabled. Standby loss is only 0.8 watts. Designed for installation. Dimensions: 45 mm long, 45 mm wide, 33 mm deep. The switching state is maintained in the event of a power supply failure. Upon restoration of the power supply, it will be defined as switched off. After installation, wait for the automatic short synchronization before connecting the switched load to the network. In addition to the radio control input via an internal antenna, this radio actuator can also be locally controlled with a conventional control button that may be installed beforehand. A glow lamp current is not permitted. Encrypted sensors can be learned in. Bidirectional radio and/or a repeater function can be activated. Any state change and received central control telegrams will then be confirmed with a radio telegram. This radio telegram can be learned into other actuators, the GFVS software, and universal displays. Scene control: With one of the four control signals from a button learned as a scene button with a double rocker, multiple FSR61 units can be switched on or off as part of a scene. The upper rotary switch in the LRN position allows for learning up to 35 radio buttons.
