1. Introduction
The GEYA GIR Mechanical Impulse Relay is designed for household and industrial applications, providing reliable control of electrical circuits. This relay operates based on pulse signals, changing the state of its contacts with each received impulse. It features two stable mechanical positions, ensuring low power consumption as continuous energization is not required once the state is set.
This product is ideal for remote control of lighting circuits and other applications where a momentary pulse is used to toggle a circuit's state. It is certified to CE and RoHS standards, ensuring quality and safety.

4.2 Outline and Installation Dimensions
The GEYA GIR Impulse Relay is designed for 35mm DIN rail mounting. The dimensions are approximately 86mm (height) x 72mm (width) x 18mm (depth). For detailed visual reference, please consult the user manual PDF.
4.3 Wiring Diagram and Sequence Diagram
The relay features terminals for the coil (A1, A2) and the main contacts (1, 2 for 1NO; 1, 3, 2, 4 for 2NO). The wiring involves connecting the line (L) and neutral (N) to the appropriate terminals, with the load connected through the main contacts. The sequence diagram illustrates how a pulse to A1/A2 toggles the state of the main contacts. For a detailed visual wiring diagram, please refer to the user manual PDF.
For comprehensive diagrams and visual instructions, please refer to the official user manual PDF: GEYA GIR Impulse Relay User Manual (PDF).
5. Operating Instructions
The GEYA GIR Impulse Relay operates by changing the state of its contacts upon receiving a momentary electrical pulse. This bistable characteristic means the relay maintains its state (either ON or OFF) until the next pulse is received.
- Initial State: When power is first applied, the relay will be in a default state (e.g., contacts open).
- First Pulse: A momentary pulse signal applied to the coil terminals (A1, A2) will cause the relay contacts to switch state (e.g., from open to closed).
- Stable State: The contacts will remain in this new state even after the pulse signal is removed.
- Subsequent Pulses: Each subsequent momentary pulse to the coil will reverse the state of the contacts (e.g., from closed to open, then back to closed, and so on).
This functionality makes it suitable for applications such as:
- Controlling lighting circuits with pushbuttons, where each press toggles the light ON or OFF.
- Remote control systems where a single signal needs to alternate between two states.

6. Maintenance
The GEYA GIR Impulse Relay is designed for long-term, maintenance-free operation under normal conditions. However, periodic checks are recommended to ensure optimal performance and safety:
- Visual Inspection: Regularly inspect the relay for any signs of physical damage, discoloration, or loose connections.
- Terminal Tightness: Ensure all wiring terminals are securely tightened to prevent overheating or intermittent operation.
- Environmental Conditions: Verify that the operating environment remains within the specified temperature and humidity ranges.
- Cleaning: If necessary, gently clean the exterior of the relay with a dry, soft cloth. Do not use abrasive cleaners or solvents.
In case of any malfunction or unusual behavior, refer to the troubleshooting section or contact qualified service personnel.
7. Troubleshooting
If you encounter issues with your GEYA GIR Impulse Relay, consider the following basic troubleshooting steps:
- Relay Not Responding to Pulse:
- Check the control voltage supply to terminals A1 and A2. Ensure it matches the relay's rated coil voltage (230V AC or 110V DC).
- Verify the pulse duration. It should be within the specified range (50ms to 1s, recommended 200ms).
- Inspect the wiring for loose connections or breaks in the control circuit.
- Ensure the pushbutton or control device is functioning correctly and providing a clean pulse.
- Contacts Not Switching or Sticking:
- Confirm that the load connected to the main contacts does not exceed the relay's rated current (16A) or switching power (4000VA).
- Check for any physical obstruction or damage to the relay's mechanism.
- If the relay has been subjected to severe overloads, its internal contacts might be damaged.
- Overheating:
- Ensure proper ventilation around the relay.
- Verify that the load current does not exceed the rated current.
- Check for loose terminal connections, which can cause resistance and heat buildup.
If the problem persists after performing these checks, it is recommended to consult a qualified electrician or contact GEYA customer support.
8. User Tips
- Optimal Pulse Duration: While the relay accepts pulses between 50ms and 1s, a pulse duration of approximately 200ms is recommended for reliable operation.
- Load Compatibility: This relay is suitable for both resistive loads (e.g., incandescent lamps, halogen lamps) and inductive loads (e.g., fluorescent lamps, discharge lamps). Always ensure the load current and power are within the relay's specifications.
- DIN Rail Mounting: The 35mm DIN rail mounting makes installation straightforward in standard electrical enclosures. Ensure it is securely clipped into place.
