Impulse switch, 2 NO contacts 16A

2 NO contacts potential free 16A/250V AC. 230 V LED lamps up to 200W, incandescent lamp load up to 2000W. Standby loss 0.03–0.4 watt only. Central control priorities selectable. Modular device for DIN-EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. Local universal control voltage 8 to 230V UC. In addition control inputs 8 to 230V UC central ON and central OFF, electrically isolated from the local input. Supply voltage same as the local control voltage. Very low switching noise. Glow lamp current starting at 110V control voltage up to 50mA in positions 1 to 3 and 5 to 7 of the rotary switch. By using a bistable relay coil power loss and heating is avoided even in the on mode. The switched consumer may not be connected to the mains before the short automatic synchronisation after installation has terminated. Maximum current across both contacts 16A for 230V. Contact position indication with LED. This starts blinking after 15 seconds in case of an inhibited pushbutton, not in position 4+8 of the rotary switch. With the upper rotary switch this impulse switch can be partly or completely excluded from central control: ZE+ZA = Central ON and Central OFF are active. You can select a response delay of 0, 1, 2 or 3 seconds for Central ON. ZE = Only Central ON is active. You can select a response ­delay of 0, 1, 2 or 3 seconds. ZA = Only Central OFF is active. ZE+ZA = No central control is active. The lower rotary switch sets several priorities. These determine which other control inputs are inhibited as long as onother control input is excited permanently. Furthermore, here it is decided if the switch position should be kept or not after a power failure: In positions 1 to 4 of the rotary switch the switch position remains unchanged, in positions 5 to 8 it is switched off. Incoming central commands are executed immediately after the powersupply returns. OFF = Permanent OFF, ON = Permanent ON. 1 and 5 = No priority. Also if central control inputs are excited permanently, it is possible to operate the device by pushing a local push-button. The last central command is executed. This is the setting ex factory. 2 and 6 = Priority for central ON and OFF. Local pushbuttons are temporarily inhibited. However, continuous excitation central OFF has priority over continuous excitation central ON. 3 and 7 = Priority for central ON and OFF. Local push-buttons are temporarily inhibited. However, continuous excitation central ON has priority over continuous excitation central OFF. 4 and 8 = Priority for permanently excited local push-button. In the meantime central commands are not executed. In these positions a glow lamp current is not permitted.
