Eltako 21400301 impulse switch ESR12Z-4DX-UC DUPLEX 4-way

With 4 independent contacts, 1 normally open contact each, 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. 2 division units = 36mm wide, 58mm deep. With the patented Eltako Duplex technology (DX), 3 of the 4 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 the terminal (N) and the outer conductors to 1(L), 3(L) or 5(L). This results in an additional stand-by loss of only 0.1 watts. If the contact is used to control switching devices which do not themselves switch at zero crossing, (N) should not be connected as the additional closing delay would otherwise have the opposite effect. Local universal control voltage 8..230V UC. With additional universal voltage control inputs central on and off for 8..230V UC, galvanically isolated from the local control inputs. With additional group control inputs on and off for 8..230V UC. Same potential as the local control inputs. Groups of these impulse switches can be controlled separately in a central control system via the group control inputs. Supply voltage same as the local control voltage. 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 switched consumers to the mains. Central commands always have priority, the local control inputs are blocked during the central command. If the supply voltage fails, the device is switched off in a defined manner. Using the upper rotary switch, this impulse switch can be fully or partially excluded from the central control: ZE+ZA = centrally on and centrally off effective, ZE = only centrally on effective, ZA = only centrally off effective, ZE+ZA = no central control effective. The middle rotary switch is used to preselect the functions of the lower rotary switch for ES and ER. ER is used to select the bracket functions. If BM is selected, it can be controlled with a motion detector; function as per the operating instructions. Not suitable for feedback with the switching voltage of a dimmer switch. Only use the ESR12DDX-UC, ESR12NP-230V+UC or ESR61NP-230V+UC relays for this. The lower rotary switch can be used to choose between 18 functions: ON = permanently ON. 4xS = 4-way impulse switch, each with 1 normally open contact, control inputs A1, A3, A5 and A7. (4xR) = 4-way switching relay with 1 normally open contact each, control inputs A1, A3, A5 and A7. 4S = impulse switch with 4 normally open contacts. (4R) = switching relay with 4 normally open contacts. 2S/WS = impulse switch with 3 normally open contacts and 1 normally closed contact. (2R/WR) = switching relay with 3 normally open contacts and 1 normally closed contact. 2WS = impulse switch with 2 normally open contacts and 2 normally closed contacts. (2WR) = switching relay with 2 normally open contacts and 2 normally closed contacts. SSa = series switch 2 + 2 normally open contacts with switching sequence 0-2-2+4-2+4+6, feedback 8. (4RR) = quiescent current relay with 4 normally closed contacts. SSb = series switch 2 + 2 normally open contacts with switching sequence 0-2-2+4-2+4+6-2+4+6+8.

(3xR+) = 3-way switching relay with 1 normally open contact each + feedback 8, control inputs A1, A3 and A5.
