Eltako ESR12DDX-UC digital multi-function surge switching relay 1+1S 21200302

1 +1 normally open contact potential-free 16A/250V AC, 230V LED lamps up to 600W, incandescent lamps 2000W. Stand-by loss only 0.03-0.4 watts. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. With the patented Eltako Duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thus drastically reducing wear. To do this, simply connect the N conductor to terminal (N) and L to 1(L) and/or 3(L). This results in an additional stand-by loss of only 0.1 watts. Universal control voltage 12..230V UC. Supply voltage same as the control voltage. The functions are entered using the MODE and SET buttons in accordance with the operating instructions and shown digitally on an LC display, and locked if necessary. The accumulated switch-on time is constantly displayed. First in hours (h) and then in months (m) with one decimal place. By using bistable relays, 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. Only for the impulse switch functions: If the supply voltage fails, the device is switched off in a defined manner depending on the setting or the switch position is retained (then + in the display next to the function abbreviation). Setting for RSM in the display guide. In addition, with these functions, the control inputs A1 and A3 can be defined as central control inputs using the MODE and SET buttons: ZA1 = central off with A1, local with A3, ZE1 = central on with A1, local with A3, Z00 = no central control. Central on with A1, central off with A3 and no local control, see function RS. In the relay functions, since the 3rd week of production in 2010 (03/10), suitable for feedback with the switching voltage of a dimmer switch. From 110V control voltage and in the settings 2S, WS, SS and GS glow lamp current up to 5mA, depending on the ignition voltage. Using the MODE and SET buttons, you can choose between 18 functions: OFF = permanently OFF. 2xS = 2-way impulse switch with 1 make contact each, control inputs A1 and A3. 2S = impulse switch with 2 make contacts. WS = impulse switch with 1 make contact and 1 break contact. SS1 = Series switch 1 + 1 normally open contact with switching sequence 0 - contact 1 (1-2) - contact 2 (3-4) - contacts 1 + 2. SS2 = Series switch 1 + 1 normally open contact with switching sequence 0 - contact 1 - contacts 1 + 2 - contact 2. SS3 = Series switch 1 + 1 normally open contact with switching sequence 0 - contact 1 - contacts 1 + 2. GS = Group switch 1 + 1 normally open contact with switching sequence 0 - contact 1 - 0 - contact 2. RS = Switch with 2 normally open contacts, with A1 = set and A3 = reset control input. 2xR = 2-way switching relay with 1 normally open contact each, control inputs A1 and A3. 2R = Switching relay with 2 normally open contacts. WR = Switching relay with 1 normally open contact and 1 normally closed contact.RR = switching relay (closed-circuit relay) with 2 break contacts. EAW = switch-on and switch-off wiping relay with 1 + 1 make contacts, wiping time 1s each. EW = switch-on wiping relay with 1 make contact and 1 break contact, wiping time 1s. AW = switch-off wiping relay with 1 make contact and 1 break contact, wiping time 1s. GR = group relay 1 + 1 make contact (relay with alternately closing contact). ON = permanently ON. Except for 2xS, 2xR and RS, control inputs A1 and A3 have the same function, unless used as central control inputs. After setting the desired function, it can be locked. An arrow to the right of the function abbreviation in the header of the display shows the locking status.
