1 normally open contact not potential-free 16A/250V AC, 230V LED lamps up to 600W, ESL up to 200W, incandescent lamps up to 2300W. Control voltage 230V and/or 8..230V UC. Switch-off warning and button permanent light can be switched on. Standby loss only 0.7 watts. With ESL optimization and multifunction. Contact switching at zero crossing to protect the contacts and lamps. In particular, this extends the service life of energy-saving lamps. By using a bistable relay, there is no coil power loss and no heating as a result, even when switched on. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. Also with galvanically isolated universal control voltage. Automatic detection of the switching type. Glow lamp current up to 50mA, depending on the ignition voltage of the glow lamps. Precise time setting 1 to 30 minutes with minute scale. Permanent light switch with the large rotary switch. After a power failure in the TLZ function setting, the lighting is switched back on if the time has not yet expired. With double connections for button and lamp, so that connections can be made either at the top and bottom or just at the bottom. If the switch-off warning is switched on, the lighting flickers starting around 30 seconds before the time expires and a total of 3 times at increasingly shorter intervals. If the permanent light button is switched on, the light can be set to permanent light by pressing the button for longer than 1 second, which switches off automatically after 60 minutes, or it can be switched off by pressing the button for longer than 2 seconds. If the permanent light button and switch-off warning are switched on, the switch-off warning only occurs after the permanent light is switched off.
