Eltako R12 Auxiliary Relay - 22100030

The two normally open (NO) contacts mean that when the relay is de-energized, the contacts are open, and when the relay is energized, the contacts close. This allows you to switch two separate circuits or to use both contacts in parallel for a single circuit requiring higher current handling (up to the device's limit).

This specific model (22100030) is designed for a 230V AC control voltage. Eltako offers other models within the R12 series with UC (Universal Control) voltage that can handle both AC and DC across a wider range.

A '1 module' width typically refers to 18mm in the context of DIN rail modules. This means the relay occupies the space of one standard 18mm module on the DIN rail, helping to standardize and optimize space in control cabinets.

Product warranty information is typically provided by the seller or manufacturer at the time of purchase. Please refer to your purchase documentation for specific warranty details.

This electromechanical relay requires a direct 230V AC control signal to operate. For remote control or integration into smart home systems, you would typically need an interface module or a different type of relay designed for low-voltage control signals or communication protocols.

The switch position indicator is a mechanical flag or lever that moves in conjunction with the relay's internal contacts, visually showing whether the relay is energized (contacts closed) or de-energized (contacts open).

This is an electromechanical relay, using physical contacts that open and close. Electronic switching relays (like Eltako's ER series) use solid-state components and have no moving parts, offering faster switching speeds and longer operational life, but sometimes with different electrical characteristics or isolation.

Verify that the control voltage is exactly 230V and is correctly connected to the input terminals. Check for any breaks in the control wiring.

Ensure the control voltage is removed. Inspect the contacts for visible damage or debris. If damaged, the relay may need replacement. Check that the load current does not exceed the 16A rating.

This is often a mechanical indicator linked to the relay state. If it's misaligned, the relay might still be functioning electrically. Check for obstructions. If the relay switches correctly but the indicator is faulty, it may indicate an internal issue requiring replacement.

Ensure the load current is within the 16A limit. Check for adequate ventilation around the relay in the control cabinet. Verify that the control voltage is stable.
