Introduction

The 1393818-6 signal relay is a single-pole-double-throw (SPDT) normally open (NO) contacts relay, designed for use in applications up to 2 amps. This signal relay offers a variety of features, including a high electrical isolation with its ceramic substrate base, as well as its ability to switch the current in either direction. This makes it a great choice for use in both AC and DC applications.

Application Field

The 1393818-6 signal relay is designed for low-power signal switching applications, such as switching electric motors, ventilation systems, and lighting. It is also suitable for use in industrial control systems, machines, and general control, monitoring and regulating applications.

In addition, this signal relay can be used for switching between two supplies, providing a simple form of redundancy. It can also be used as a low-power switch for switching between two circuits, in order to increase system flexibility. Furthermore, the signal relay can be used to provide a low-cost, non-polarized switching of a signal line.

Working Principle

The 1393818-6 signal relay works on an electromechanical principle, where a coil electromagnet is energized when power is applied, causing a metal armature to be attracted to it. When the armature is moved, it causes the contacts of the relay to open and close as necessary, thus switching the current in one direction or the other.

More specifically, the relay has two sets of normally open (NO) contacts which are connected to either the supply or output when the electromagnet is energized. When the contacts are opened, the supply or output is disconnected from the other side, and vice versa. This switching principle allows the relay to be used for switching between two supplies, as well as for switching on electrical motors or other low-power devices.

It is important to note that the 1393818-6 signal relay is designed to be used with a voltage that is lower than the breakdown voltage of the coil contacts.

Advantages

The 1393818-6 signal relay offers a number of advantages over traditional mechanical switches and other relays, including:

• Lower contact bounce
• Lower power consumption
• Higher electrical isolation
• High contact reliability
• Low cost

The lower contact bounce helps to reduce transient high-voltage spikes, while the lower power consumption increases the energy efficiency of the relay. The higher electrical isolation also increases the safety of the relay and helps to protect the relay contacts from arcing or accidental contact with the energized wires.

The high contact reliability of the signal relay also ensures that the relay will remain reliable over time, while the low cost makes it an ideal choice for a wide variety of applications.

Conclusion

The 1393818-6 signal relay is a single-pole-double-throw (SPDT) normally open (NO) contacts relay, designed for use in applications up to 2 amps. This signal relay offers a variety of features, including a high electrical isolation with its ceramic substrate base, as well as its ability to switch the current in either direction. This makes it a great choice for use in both AC and DC applications, such as electric motors, ventilation systems, and general control, monitoring and regulating applications.

The 1393818-6 signal relay also offers a number of advantages, including lower contact bounce, lower power consumption, higher electrical isolation, higher contact reliability, and low costs. As such, this signal relay is an excellent choice for use in a variety of low-power applications.
