Electromechanical relay Eltako R12-110-230V — 1 NO + 1 NC contacts, 230 V coil

Eltako R12-110-230V is an electromechanical relay with one normally open (NO) contact and one normally closed (NC) contact driven by a 230 V AC coil. It provides mechanical switching for electrical circuits in DIN-rail installations and control panels, enabling separation of switching and control circuits and offering straightforward integration into automation and building control systems.

Advantages

The relay delivers reliable mechanical contact switching with clear NO and NC outputs, suitable for applications that require distinct make and break circuits. Its coil rated for 230 V AC matches common mains voltages, reducing the need for additional control transformers. The compact design supports mounting in standard DIN-rail enclosures, while the simple electrical interface eases installation and replacement.

How to use

Mount the relay on a standard DIN-rail inside the control panel and connect supply and load wiring according to the circuit diagram for NO and NC contacts. Apply the 230 V AC coil voltage to activate the switching action; when the coil is energized the NO contact closes and the NC contact opens. Ensure wiring is performed with power off and that conductor sizes and protective devices are selected according to the connected load and applicable electrical standards.

Recommendations

Use the relay within its rated coil voltage and implement appropriate overload protection and fusing for switched circuits. Verify contact ratings against actual load currents and consider adding suppression components for inductive loads to extend contact life.
