 Product Description

1 NO contact potential free 16 A/250 V AC, incandescent lamp load up to 2000 W. No standby loss.

Modular device for DIN-EN 60715 TH35 rail mounting.
1 module = 18 mm wide, 58 mm deep.
State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high
capacity of special relays.

With the patented Eltako Duplex technology (DX) the normally potential-free contacts can still switch in zero passage when switching 230 V AC 50 Hz and therefore drastically reduce wear. Simply connect the neutral conductor to the terminal (N) and L to 1(L) for this. This gives an standby consumption of only 0.1 Watt.

If the contact is used for controlling switching devices which do not perform zero passage switching themselves, (N) should not be connected because the additional closing delay otherwise causes the opposite effect.
Universal control voltage 8 to 230 V UC.
Very low switching noise.
Contact position indicator with LED.
Same terminal connection as electromechanical switching relay R12-100-.

By using a bistable relay coil power loss and heating is avoided even in the on mode.

The relay contact can be open or closed when putting into operation. It will be synchronised at first operation.

This relay is not suitable to feed back the switching voltage signal of a dimmer switch.
Use only relays ESR12DDX-UC, ESR12NP-230V+UC or ESR61NP-230V+UC for this purpose.

The electronics does not have an internal power supply and therefore no standby loss. The microcontroller is activated when the control contact closes. This switches the bistable relay to the correct direction. The bistable relay switches back either when the control contact opens or when the control voltage falls.

Technical Details

Control voltage AC 8 to 253V
Control voltage DC 10 to 230V
Rated switching capacity 16A/250V AC
Incandescent lamp load and halogen lamp load(1) 230V 2000W
Fluorescent lamp load with KVG* in lead-lag circuit or non compensated 1000VA
Fluorescent lamps with KVG* shunt-compensated or wih EVG* 500VA
Compact fluorescent lamp with EVG* and energy saving lamps ER12DX - 15x7W, 10x20W(2)
  ER12-200/110 - I on ≤ 70A/10ms3(3)
Standby loss none
(1) For lamps with 150W max.
(2) If zero passage switching is activated, otherwise same as for ER12-200/110.
(3) For electronic ballast gears a 40fold inrush current has to be calculated. For steady loads of 1200W use the current-limiting relay SBR12.
* EVG = electronic ballast units / KVG = conventional ballast units
