Eltako ER12DX-UC REG-Steuerrelais – Compact 230VAC Switching Relay for Wired Smart Home Installations
The Eltako ER12DX-UC is a potential-free switching relay designed for 230VAC circuits with a 16A rated current. It serves as a compact control component in building automation and smart home wiring, enabling remote switching of loads such as lights, heaters, and small appliances through a wired control signal.
Potential-free contact with 16A switching capacity at 250V AC handles standard household and light commercial loads reliably
Compact relay design fits into standard DIN rail or flush-mount installations without occupying valuable space
Wired system communication ensures a direct, interference-free control signal without reliance on wireless protocols
Blue housing provides clear visual identification during installation and maintenance in multi-device setups
Das zeichnet das ER12DX-UC aus
Unlike smart-home-capable relays that require a hub or gateway, this unit operates as a pure wired switching actuator — no protocol overhead, no compatibility configuration, no firmware updates. The potential-free contact design ensures that the relay switches the load circuit without ever energising the control circuit, which protects downstream electronics and reduces fire risk in permanent installations.
Ideal für...
Electricians and building technicians integrating relay-based switching into new or retrofit wiring systems. The 16A rating makes it suitable for controlling lighting circuits, small HVAC actuators, and power outlets in residential and light commercial buildings where a simple, reliable wired switch is needed without the complexity of a smart-home ecosystem.
Anwendung von Eltako ER12DX-UC
Mount the relay on a DIN rail or in a flush-mount box within the distribution board
Connect the 230VAC load circuit to the relay's switched output terminals
Wire the control signal to the relay's input terminals — the potential-free contact activates the load
Verify the blue indicator shows correct switching state after energising the control circuit
Eltako is a German manufacturer specialising in electrical switching and control components for building automation. The brand supplies relays, contactors, and timer switches predominantly to the European professional installation market. Eltako products are designed for DIN-rail mounting in distribution boards and are widely used in residential and commercial wiring projects.
It is a potential-free switching relay for 230VAC circuits, used to remotely switch loads such as lights, heaters, and small appliances in building automation installations.
No. The relay has no smart-home protocol or wireless communication capability. It operates as a pure wired switching actuator controlled by a direct electrical signal.
