Signal relays, up to 2 amps, are essential components in a variety of industrial applications. It is a type of device designed to switch electrical signals between two circuits quickly and accurately based on a control signal. In the following article, a 1617127-4 signal relay, which is a 12 V DC operated, 9 pin signal relay, is discussed in order to demonstrate its applications and principles of working.

Overview

The 1617127-4 (C1617127-4) is a 12 V DC operated miniature signal relay that features a pull-in voltage of 2.5–3.3 VDC and a release voltage of 1.2–2.1 VDC. Its maximum switch capacity is 2 A at 30 VDC and 1.5 A at 125 VAC. The relay features nine pins for signal input and output. It relies on an electromechanical solenoid pull-in mechanism working in conjunction with a fixed and movable contact, enabling high contact pressure, contact maintenance, and breaking the circuit.

Applications

The signal relay is commonly used in sensors, alarm systems, testing equipment, electronic switches, and other small-sized electrical circuits. Its low power consumption and robust design make it suitable for automotive, telecommunication, and consumer applications. Additionally, its high switching efficiency and fast switching speed are beneficial in controlling time-sensitive applications.

Advantages

The 1617127-4 signal relay offers several advantages. Its low profile design and low power consumption reduce energy costs and extend the life of the relay. Moreover, its 9 pin design offers superior performance in comparison to standard 3 pin designs. The choice of three coil voltages allows users to optimize their applications for maximum efficiency and minimum cost. Additionally, its low insertion force during assembly and high contact pressure reduce contact bounce and arcing.

Working Principle

The 1617127-4 signal relay works through an electromechanical solenoid pull-in mechanism. When the input signal (control voltage) is applied, the field coil connected to the signal relay creates a magnetic field which actuates the armature and pulls it towards the fixed contact. As the armature moves, the movable contact attached to it makes contact with the fixed contact. Thus, the circuit is completed and the output signal is generated. When the input signal is removed, the magnetic field is also removed and the movable contact moves away from the fixed contact, breaking the circuit.

Conclusion

The 1617127-4 is a 12 V DC operated miniature signal relay capable of switching up to 2 A at 30 VDC and 1.5 A at 125 VAC. It is used in a variety of applications due to its robust and energy efficient design. Its pull-in voltage of 2.5–3.3 VDC and release voltage of 1.2–2.1 VDC make it suitable for use with time-sensitive applications. The relay works through an electromechanical solenoid pull-in mechanism, and its nine pin design offers superior performance in comparison to conventional three pin designs.
