1. Einleitung
The Eltako ES12Z-200 is a modular impulse relay designed for inline installation on a DIN-EN 50 022 rail. This device features galvanically isolated working contacts and centralized control inputs, allowing for local control with a different phase and voltage than the centralized system. It includes a rotary switch for setting different priorities between control inputs and determining the device's behavior (switch off or maintain position) after a power failure.
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Eltako ES12Z-200 impulse relay.
2. Hauptmerkmale

5. Installation
5.1 Montage
The Eltako ES12Z-200 is designed for mounting on a standard DIN-EN 50 022 rail. Ensure sufficient space for ventilation and access to terminals.
5.2 Schaltplan
Refer to the wiring diagram below for correct electrical connections. The device supports both local and centralized control inputs with galvanic isolation.
Bild 1: Wiring diagram for the Eltako ES12Z-200 impulse relay. This diagram illustrates the connections for the main power supply (L, N), local control input, centralized control inputs (central on, central off), and the output contacts (1, 2). It also shows the internal circuitry for the control voltage and the 16A/250V output rating.
5.3 Verbindungsschritte
- Stromversorgung: Connect the live (L) and neutral (N) wires to the designated terminals as shown in the diagram. The device operates with a supply voltage range of 8-230V AC/DC.
- Lokale Steuerung: Connect your local push-button or switch to the 'local on/off' input. This input typically requires a control current of up to 150mA for neon lamps from 110V.
- Zentralisierte Steuerung: Connect centralized 'on' and 'off' control signals to the respective terminals. These inputs are galvanically isolated, allowing for different control voltages oder Phasen.
- Ausgangskontakte: Connect the load (e.g., lighting circuit) to the output contacts (1 and 2). The relay provides two normally open (NO) contacts with a maximum current rating of 16A at 250V.
- Überprüfung: Double-check all connections for correctness and security before applying power.
6. Bedienung
6.1 Grundlegende Funktionalität
The Eltako ES12Z-200 functions as an impulse relay. A brief pulse to any activated control input (local, central on) will toggle the state of the output contacts. A pulse to the central off input will switch the contacts to the OFF state.
6.2 Priority Selection and Power Failure Behavior
The device features a rotary switch on its front panel to configure priority settings for control inputs and define behavior during power failures.
Bild 2: Nahaufnahme view of the Eltako ES12Z-200 rotary switch. This switch allows users to select different priority levels for control inputs and configure the relay's response to power outages, such as switching off or maintaining its current state.
The rotary switch allows you to:
- Set different priority levels for the various control inputs (e.g., local vs. centralized).
- Determine the relay's state after a power failure: either switch off or maintain its last switching position upon power return. Consult the specific markings on your device for detailed settings.
7. Wartung
The Eltako ES12Z-200 impulse relay is designed for long-term, maintenance-free operation under normal conditions. However, periodic checks are recommended:
- Sichtprüfung: Periodically inspect the device for any signs of physical damage, overheating, or loose connections.
- Reinigung: Reinigen Sie die Außenseite des Geräts bei Bedarf vorsichtig mit einem trockenen, weichen Tuch. Verwenden Sie keine flüssigen Reiniger oder Lösungsmittel.
- Anschlussdichtheit: Ensure all terminal screws remain tight to prevent poor contact and potential overheating.
Always disconnect power before performing any inspection or cleaning.
8. Fehlerbehebung
If you encounter issues with your Eltako ES12Z-200, refer to the following table for common problems and solutions:
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Relay does not respond to control input. | No power supply; incorrect wiring; faulty control switch; control voltage outside range. | Check power supply to L and N terminals. Verify all wiring connections against the diagram. Test the control switch. Ensure control voltage liegt im Bereich von 8-230V AC/DC. |
| Die Last schaltet nicht ein/aus. | Faulty load; incorrect load wiring; overloaded contacts. | Check the load (e.g., light bulb). Verify wiring to output contacts. Ensure load current does not exceed 16A. |
| Relay switches erratically. | Interference; loose connections; faulty device. | Check for sources of electrical interference. Tighten all terminal connections. If problem persists, the device may be faulty and require replacement. |
| Device gets excessively hot. | Overloaded contacts; poor ventilation; loose connections. | Reduce load if exceeding 16A. Ensure adequate ventilation around the device. Tighten all connections. |
