Noiseless solid-state relay, not potential-free, 230V LED lamps up to 400W, incandescent lamps 400W, off-delay with switch-off warning and permanent light with push-button switchable. Stand-by loss only 0.3 watts. For flush mounting. 45mm long, 45mm wide, 18mm deep. Supply, switching and control voltage 230V. Contact switching at zero crossing. If the supply voltage fails, the switch is switched off in a defined manner. In the ER function, the relay switches back on when the voltage returns and the control input is active. A glow lamp current at the control input is not permitted. With automatic electronic overtemperature shutdown. For a load < 1W, a GLE must be connected in parallel to the load. The desired function of this impulse switching relay is selected using the upper rotary switch: ER = switching relay. ESV = impulse switch. If necessary with release delay, then + button permanent light = ESV with button permanent light. + Switch-off early warning = ESV with switch-off early warning. + button permanent light and switch-off early warning = ESV with button permanent light and switch-off early warning. The LED flashes as soon as a new setting range is reached when turning the rotary switch to help you find the desired position. The LED lights up constantly when the relay is switched on. When the button permanent light is switched on, you can set it to permanent light by pressing the button for longer than 1 second, which is signaled by the lamp flickering briefly. After 2 hours, the permanent light switches off automatically, or can be switched off beforehand by pressing the button briefly. When the switch-off early 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. During the switch-off early warning, you can switch it on again by pressing the button. If the switch-off pre-warning and the permanent light button are switched on, the switch-off pre-warning only occurs after the permanent light is automatically switched off. The lower rotary switch can be used to set the release delay from 2 to 120 minutes in the ESV function. In the infinite position, the normal impulse switch function ES without release delay, without permanent light button and without switch-off pre-warning. In the ER function, a switch-on wiping time of 2 to 120 seconds can be set. After the wiping time has elapsed, the relay switches off automatically. In the infinite position, the normal relay function ER without wiping time.
