1. Introduction
The GEYA GIR Mechanical Impulse Relay is a bistable latching relay designed for automatic control in household and industrial applications. It operates by changing its contact state (ON/OFF) with each electrical impulse received by its coil, maintaining its state without continuous power, thus offering zero energy consumption in its stable positions. This relay is ideal for controlling lighting circuits and other loads via pushbuttons.
Key features include:
- Bistable mechanical positions for stable operation.
- Zero energy consumption in stable states.
- Can be controlled by an unlimited number of pushbuttons.
- Suitable for resistive and inductive loads.
2. Safety Information
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel in accordance with all local and national electrical codes.
- Always disconnect power before installing, wiring, or servicing the relay.
- Ensure the relay's voltage and current ratings match your application requirements.
- Do not operate the relay in environments exceeding its specified temperature or humidity limits.
- Verify all connections are secure to prevent loose contacts and potential hazards.
3. Product Overview
The GIR-16 series relays are available in 1NO (normally open) and 2NO configurations, indicated by GIR-16/10 and GIR-16/20 respectively. Each unit features terminals for coil connection (A1, A2) and load contacts (1, 2 for 1NO; 1, 2, 3, 4 for 2NO). A manual override switch (OFF/auto) is present on the front panel.

5. Setup and Installation
The GEYA GIR Mechanical Impulse Relay is designed for DIN rail mounting (35mm type). Follow the steps below for proper installation:
- Mounting: Securely attach the relay to a standard 35mm DIN rail in your electrical panel.
- Wiring: Refer to the wiring diagram below for correct connections.
- Connect the Line (L) and Neutral (N) to the appropriate terminals as shown.
- Connect the control impulse (e.g., from a pushbutton) to the coil terminals A1 and A2.
- Connect the load circuit to the output contacts (1, 2 for 1NO; 1, 2, 3, 4 for 2NO).
- Ensure proper grounding (E) if applicable.
- Verify: Double-check all connections for tightness and correctness before applying power.
Wiring Diagram Details: The diagram illustrates a typical connection for controlling a light. An impulse to A1-A2 (coil) will toggle the state of the contacts (1-2 or 1-2 and 3-4). The sequence diagram shows that a pulse on A1-A2 reverses the state of the output contacts.
6. Operating Instructions
The GEYA GIR Mechanical Impulse Relay operates based on momentary electrical impulses:
- Power On: Once correctly wired and power is supplied, the relay will be in one of its two stable mechanical positions (either contacts open or closed).
- Switching State: Apply a momentary electrical impulse to the coil terminals (A1 and A2). The relay's internal mechanism will switch the position of its contacts. For example, if the contacts were open, they will close, and vice-versa.
- Maintaining State: The relay will maintain its new contact position even after the impulse is removed, requiring no continuous power to hold the state.
- Manual Override: The relay features a manual switch on the front panel, typically labeled 'OFF' and 'auto'. This allows for manual control or to set the relay to automatic (impulse-controlled) mode.
7. Maintenance
The GEYA GIR Mechanical Impulse Relay is designed for long-term, maintenance-free operation. However, periodic checks are recommended:
- Visual Inspection: Periodically inspect the relay for any signs of physical damage, discoloration, or loose connections.
- Cleaning: Ensure the relay and its surroundings are free from dust and debris, which can impede proper operation or cause overheating. Use a dry, soft cloth for cleaning.
- Terminal Tightness: Occasionally check that all terminal screws are tight, especially in environments with vibration.
Do not attempt to open or repair the relay yourself. Refer to qualified service personnel for any issues beyond basic inspection.
8. Troubleshooting
If the relay is not functioning as expected, consider the following:
- Relay Not Switching:
- Check if the control impulse is being correctly applied to A1 and A2.
- Verify the control voltage (230V AC or 110V DC) matches the relay's coil specification.
- Ensure the pulse duration is within the specified range (50ms to 1s, recommended 200ms).
- Check the manual override switch; ensure it is in the 'auto' position if automatic control is desired.
- No Power to Load:
- Confirm that the main circuit voltage (24-250V AC) is present at the input terminals.
- Check the load connections (1, 2, 3, 4) for continuity and proper wiring.
- Ensure the relay contacts are actually switching (a click sound might be audible, or use a multimeter to check continuity).
9. User Tips
- Coil Voltage Compatibility: The GEYA GIR Mechanical Impulse Relay is specified for a coil control voltage of 230V AC or 110V DC. Ensure your control circuit provides one of these exact voltages. For example, a 110V AC control signal is NOT compatible with the 110V DC coil variant. Always match the coil voltage to your power supply.
- Multiple Pushbuttons: Take advantage of the relay's design to control a single lighting circuit from multiple locations using simple momentary pushbuttons wired in parallel to the coil.
- Pulse Duration: While the relay tolerates a pulse duration between 50ms and 1s, a pulse around 200ms is generally recommended for optimal and reliable switching.
