The Eltako ES12Z-200-UC impulse relay is designed for electrical control applications, offering efficient switching for lighting and other loads. It is ideal for homeowners, electricians, and building managers seeking reliable and energy-efficient control. A key benefit is its low standby loss and ability to handle high incandescent lamp loads, though it requires a DIN rail for mounting. This device features two potential-free make contacts, bi-stable relay technology for zero coil loss, and compatibility with a wide control voltage range.

The primary advantage is zero coil power consumption when the relay is energized, meaning it doesn't generate heat and saves energy. It maintains its state until a new impulse is received.
While not specifically rated for LED, if the total wattage of the LED lights does not exceed the relay's capacity (e.g., 16A general load) and the power factor is suitable, it may work. However, for precise LED control, specialized relays might be more appropriate.
It means the contacts are isolated from the relay's internal control circuitry and power supply. They can be connected to any voltage or ground as needed for the load.
These inputs, electrically isolated from the local control, allow a master switch or system to override local commands and turn all connected devices ON or OFF simultaneously.
The general rated switch current is 16A. For loads with a power factor of 0.6 (like some motors or transformers), the maximum switching current is 4A.
No, the supply voltage is the same as the control voltage (8-230V AC/DC), simplifying installation.
It occupies one modular spacing unit, which is 18mm wide.
Verify that the control voltage is within the 8-230V AC/DC range and correctly connected to the input terminals. Ensure the load wiring is secure and the load itself is functional.
Check for any voltage present on the control input terminals when the external switch is in the off position. Inspect for damage to the internal relay contacts or control circuitry. Ensure correct wiring for central ON/OFF functions if used.
Disconnect power immediately. Check if the connected load exceeds the specified limits (e.g., 2000W incandescent, 16A total current). Ensure adequate ventilation around the device. If the issue persists, the unit may be faulty and require replacement.
Ensure all connections are tight and free of corrosion. Verify that the control signal is clean and stable. If used for frequent switching, confirm the load is within the rated switching current, especially for inductive loads (4A max at cos phi = 0.6).
