A signal relay or switch is an electrical component that is used to transfer electrical energy or signals from one part of a circuit or network to another. It might be a mechanical device, an electromechanical device or an electronic device, depending on the type of signal being transferred. The 3SBH1261A2 is an electromechanical signal relay used in an array of applications and has numerous advantages.

Application Field

The 3SBH1261A2 signal relay is a multipole signal relay capable of carrying up to 2Amps when properly applied. It is available in a variety of form factors, which include DIN mount, rail mount, plug-in and panel mount. Due to its design, it is also able to withstand vibration, shocks, and temperatures up to 85°C. This makes it the ideal choice for automation and process automation applications, such as in robotics, computer networks, automated assembly lines, and process control. It can also be used in other industrial applications and telecommunication systems.

Working Principle

The 3SBH1261A2 signal relay uses an inductive coil to create a magnetic field when the power supply is turned on. This magnetic field causes the poles of the relay to move, closing the contacts and completing the circuit. The 3SBH1261A2 has two types of contact arrangements, normally open (N/O) and normally closed (N/C). The N/O switch contacts are normally closed when the power is off, while the N/C switch contacts are normally open when the power is off.

When the relay is activated, the inductive coil creates a magnetic field that causes the poles to move and complete the circuit. Depending on the contact arrangement, the switch will either open or close. In the N/O configuration, the switch will open when the relay is energized, while in the N/C configuration, the switch will close when the relay is energized.

The 3SBH1261A2 is also designed with a fail safe feature. This feature ensures that, in case of a power surge or loss, the relay will remain in its de-energized position, ensuring the safety of any equipment connected to it. This means that once the power is restored, the relay will return to its normal state, as though there never had been a power problem.

Conclusion

The 3SBH1261A2 is a multi-purpose, multipole electromechanical signal relay. It is built to handle up to 2Amps, and withstand vibration, shocks, and temperatures up to 85°C. It is perfect for applications in automation and process automation, but can also be used in other industrial and telecommunication systems. The 3SBH1261A2 comes with a fail safe feature that ensures safety in the event of a power surge or loss.
