Eltako Electronic Switching Relay ER12-100-230V 16A 1NO 230V AC DIN Rail 22100000

For switching loads up to 16 A with minimal standby consumption, the Eltako ER12-100-230V electronic switching relay stands apart from conventional electromechanical relays. Its silent, wear-free operation and compact 1-module DIN rail housing make it ideal for lighting and heating control in residential and commercial installations. The relay features a single normally open contact, controlled by a 230 V AC input, and handles a wide range of lamp types including LED, incandescent, halogen, and fluorescent loads. With a standby loss of only 0.8 W and a maximum switching frequency of 600 operations per hour, it offers both energy efficiency and reliable performance in demanding switching applications.

Highlights

• Electronic switching relay with 1 NO contact, 16 A / 250 V AC rating
• Control voltage 230 V AC, suitable for direct mains switching
• Silent operation with no mechanical wear, extending service life
• Compact DIN rail mounting, width only 1 module (18 mm)
• Low standby loss of 0.8 W, reducing energy costs
• Supports LED lamps up to 200 W, incandescent/halogen up to 2000 W
• High switching frequency up to 600 operations per hour
• Wide ambient temperature range from -20°C to +50°C

In daily use

Installation is straightforward: the ER12-100-230V snaps onto a standard 35 mm DIN rail (EN 60715 TH35) and connects via screw terminals. It is commonly used to switch lighting circuits, heating elements, or small motors where silent operation is preferred. The relay's electronic design eliminates contact bounce and arcing, making it suitable for frequent switching. Its IP20 protection class means it should be installed inside a distribution board or enclosure. The device requires no minimum load for reliable operation, but a minimum switching power of 100 mA at 10 V AC/DC is specified for contact wetting.
