Product Information
Full details
This Omron MY4 4PDT plug-in relay is designed for engineers and technicians requiring robust control in automation and industrial applications. Its key benefit is the 4PDT (4-Pole Double-Throw) configuration, offering multiple independent switching paths for complex circuit control. A potential caveat is its specific 12VDC control voltage, requiring a compatible power source. This 14-pin relay features a 6A current rating, mechanical indicator for status, and plug-in terminals for straightforward installation and maintenance.

Extended Product Information
FAQs
What is a 4PDT configuration?
4PDT stands for 4-Pole Double-Throw. It means the relay has four independent sets of contacts, and each set can switch between two circuits (normally open or normally closed).
What type of socket is required for this relay?
This 14-pin MY4 relay requires a compatible 14-pin Omron MY4 series relay socket, which is typically panel-mounted.
What is the maximum AC and DC voltage this relay can switch?
The maximum switching voltage for this relay is 250V AC and 220V DC.
Can this relay be used with AC control voltage?
No, this specific model (MY4 5714A) is designed for a 12VDC control voltage coil. Other Omron MY4 variants are available for AC control.
How do I determine if the relay is energized?
You can visually check the mechanical indicator on the relay. When energized, the indicator typically shows a different position or color compared to when de-energized.
What is the coil resistance of this relay?
The coil resistance for this 12VDC model is 165 Ω.
Is this relay suitable for continuous duty?
Yes, plug-in relays like the Omron MY4 series are generally designed for continuous duty applications when operated within their specified voltage and current ratings.
Troubleshooting
Relay does not energize when control voltage is applied.
Verify the 12VDC supply is correctly connected to the coil terminals. Check for proper voltage at the terminals using a multimeter. Ensure the coil resistance (165 Ω) is within tolerance.
Contacts do not switch when relay is energized.
Confirm the relay is receiving the correct coil voltage. Check if the mechanical indicator shows the relay is energized. Inspect the socket wiring for loose connections. The relay may be faulty and require replacement.
Intermittent operation or failure to switch.
Check for loose wiring at the socket. Ensure the relay is securely seated in its socket. Environmental factors like vibration or extreme temperatures could be a cause. Clean the terminals if corrosion is present.
Mechanical indicator is stuck or not moving.
This often indicates an internal issue with the relay coil or mechanism. While the relay might still function electrically, the indicator's failure suggests potential internal wear or damage. Consider replacement.
Pros and Cons
Pros
- Versatile 4PDT configuration for complex switching.
- Reliable performance for industrial applications.
- Easy installation and maintenance due to plug-in design.
- Visual confirmation of relay status via mechanical indicator.
- Compact form factor suitable for space-constrained environments.
Cons
- Specific 12VDC coil voltage may not suit all systems.
- 14-pin configuration requires a specific socket.
- Not suitable for very high current or high voltage switching.
- Mechanical indicator can be a point of failure in harsh environments.
Setup, Compatibility & Care
Setup:
- Ensure the power source matches the relay's control voltage (12VDC).
- Select an appropriate Omron MY4-series socket (not included) for the 14-pin relay.
- Wire the control circuit to the coil terminals (e.g., pins 1 and 2) and the load circuits to the contact terminals on the socket according to the wiring diagram.
- Firmly plug the MY4 relay into the wired socket.
Compatibility:
- Control Voltage: Requires a stable 12VDC power supply.
- Load Voltage/Current: Max switching voltage is 250V AC / 220V DC. Max switching current is 6A.
- Mounting: Requires a compatible 14-pin relay socket, typically panel-mounted.
Care:
- Keep the relay clean and free from dust and excessive moisture.
- Avoid exposing the relay to extreme temperatures or vibration beyond specified operating limits.
- Periodically inspect wiring connections to the socket for security and signs of corrosion.
- Ensure the mechanical indicator operates freely.
