Signal Relays, Up to 2 Amps – C93421 Application Field and Working PrincipleThe Czech Republic-based one of the most reliable producers of industrial relays C93421 is a series of signal relays that are capable of switching up to 2 Amps. These relays are specifically designed for lightweight, low power general purpose applications, making them ideal for a wide variety of applications.This type of relay is commonly used in controlling the operation of heavy-duty electrical appliances such as air conditioners, dishwashers, and washing machines; and in operating large motors. Signal relays such as the C93421 are typically connected to a control signal, such as a temperature, pressure, or voltage signal, for controlling its operation. In addition to their wide range of applications, the C93421 relays are also extremely reliable and efficient in operations.The C93421 signal relay is a single-pole, single-throw (SPST) type of relay which provides a dry-contact, no-voltage operation. The relay is rated with switching current at 2 A and a voltage rating of 250 VAC, making it suitable for various levels of loads. It is designed with a low-profile form factor of 15 x 15 mm, making it particularly useful in installation in tight spaces. The relay is also protected against shorts and overvoltages, with a thermal dissipation of 5.7mW and a typical operating temperature range from -20°C to +85°C.The working principle of the C93421 signal relay is based on the electromagnetic theory. In this type of relay, a coil and core are used for generating an electromagnetic field. When the relay is energized, the coil creates a controlled electrical current through the core, generating a strong electromagnetic field around it. This field is then used to push and pull an armature which acts as a switch, completing the circuit. The C93421 relay also consists of a contact arm or switch mechanism, which is affixed to the armature. When the relay is energized, the armature moves the switch and contacts close, energizing the connected circuit. An important feature of the C93421 is that it comes with a holding or latching contact, which keeps the circuit energized even when the power is turned off.The C93421 signal relay is one of the most reliable and efficient options of electrical components for controlling the operation of electrical appliances. The compact size, low power usage, and incredibly versatile design of this relay make it ideal for a wide range of applications. Furthermore, its low-profile form factor and the ability to latch the contacts allows for tight installation in even the most difficult of locations.
