What is a Signal Relay?
A signal relay is used to control low voltage and low current circuits. It separates the control signal from the load side to ensure safety. Signal relays are key in telecom, test, and measurement systems.
Key Features
- 5V DC coil voltage
- Handles up to 2A current
- Double Pole Double Throw (DPDT) contacts
- Small size for tight PCB space
- High insulation and long life
- Reliable performance in harsh temperatures
Benefits of Signal Relay
The DS2Y-S-DC5V relay is great for safely switching signals in compact electronic circuits. It uses low power, provides high isolation, and works well in rough conditions.
Key Benefits:
- Saves space on PCBs
- Uses low voltage to switch high current
- Increases safety with contact separation
- Long service life
- Works in both cold and hot environments
Applications
- Telecom systems
- Test and measurement devices
- Home automation systems

How to Use?
Install the DS2Y-S-DC5V on a PCB using its through-hole pins. Connect the 5V DC supply to its coil pins. When the coil is powered, the relay switches the output circuit. It is important to use the relay within its rated voltage and current.
Cautions
- Don’t apply voltage above 5V to the coil
- Protect from strong vibration or impact
- Avoid exposure to moisture
- Mount carefully to avoid bending the pins
- Do not overload the contact terminals
