Impulse changeover switch DIN rail Eltako ESR12Z-4DX/110-240V 4 makers 16 A 2000 W 1 pc(s)

With 4 independent contacts, each 1 NO potential-free 16A/250V AC, 230V LED lamps up to 600W, light bulbs 2000W. Stand-by loss only 0.03-0.4 watts. DIN-EN 60715 TH35 DIN rail mounting device. 2 divisions = 36mm wide, 58mm deep. With the patented Eltako duplex technology (DX), 3 of the 4 normally floating contacts can still switch 50Hz in zero point when switching from 230V AC and thus drastically reduce wear. Simply connect the N conductor to the terminal (N) and the external conductor to 1(L), 3(L) or 5(L). This results in an additional standby loss of only 0.1 watts. If the contact is used to control switching devices which do not switch in the zero-crossing mode, (N) should not be connected, as the additional closing delay will otherwise cause the opposite effect. Local universal control voltage 110-240V AC. With additional universal voltage control inputs centrally ON and OFF for 110-240V AC, galvanically isolated from the local control inputs. With additional group control inputs ON and OFF for 110-240V AC. Same potential as the local control inputs. Groups of these surge current switches can be controlled separately in a central control system via the group control inputs. Supply voltage like the local control voltage. The use of bi-stable relays means that even when switched on, there is no coil power loss and no heat up through it. After installation, wait for the automatic short synchronization before connecting any connected loads to the mains. Central commands always have priority, the local control inputs are blocked during the central command. In the event of a power supply failure, the power is switched off in a defined manner. With the upper rotary switch, this surge switch can be completely or partially excluded from the central control: ZE+ZA = centrally ON and centrally OFF, ZE = only centrally ON, ZA = only centrally OFF active, ZE+ZA crossed out = no central control effective. With the middle rotary switch, the functions of the lower rotary switch are pre-selected for ES and ER. Use IT to select the clamp functions. If BM is selected, a motion detector can be controlled, function according to the operating instructions. Not suitable for feedback with the switching voltage of a dimmer switch. Use only relays ESR12DDX-UC, ESR12NP-230V+UC or ESR61NP-230V+UC. With the lower rotary switch you can select between 18 functions: ON = Duration ON. 4xS = 4-way surge current switch with 1 normally open contact each, 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 NO contact. (4R) = switching relay with 4 normally open contacts. 2S/WS = electric shock 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 = surge current switch with 2 closer and 2 opener. (2WR) = switching relay with 2 NO contacts and 2 NC contacts. SSA = series switch 2 + 2 NO with switching sequence 0-2-2+4-2+4+6, feedback signal 8. (4RR) = quiescent current relay with 4 normally closed contact. SSB = series switch 2 + 2 NO with switching sequence 0-2-2+4-2+4+6-8+4+6+2. (EW) = Switch-on wiping relay with 3 closer and 1 opener, wiping time 1s. GS = group switch. Switching sequence 0-2-0-4-0-6-0. Feedback 8. (AW) = Switch-off wiping relay with 3 NO contacts and 1 NC contact, wiping time 1s. RS = switch with 4 closer, A1 = set and A3 = reset control input. (GR) = group relay 1 + 1 + 1 +1 closer. 3xS+ = 3-way surge current switch each with 1 NO contact + Feedback 8, control inputs A1, A3 and A5. (3xR+) = 3-way switching relay with 1 normally open contact each + Feedback 8, control inputs A1, A3 and A5.
