Signal Relays, Up to 2 Amps

Signal relays and solenoids are devices commonly used in electronic applications. A signal relay is a device that routes high-voltage, low-current signals to the motor drive or load. Signal relays are versatile and can be easily integrated into operating systems. One such signal relay is the 3SAT1303A2.

3SAT1303A2 Application Field and Working Principle

The 3SAT1303A2 is an normally opened low-power signal contactor. It is suitable for applications requiring low currents and high voltages. It is available in two contact ratings- one capable of up to 2 Amp (2A) AC/DC at 250 VAC and the other up to 1 Amp (1A) AC/DC at 250 VAC.

The 3SAT1303A2 is a traditional signal relay that utilizes an electromagnetic field to activate an internal switching mechanism. When the power source is connected, the electromagnetic field is activated, causing the switching mechanism to be triggered. This triggers the opening or closing of the contacts. When the current flows into the relay, the contacts are opened. When the current stops flowing, the contacts are closed.

The 3SAT1303A2 is available in a variety of designs and sizes. It features a non-volatile, solid-state switch that can handle up to 1A AC/DC at 250 VAC and up to 2A AC/DC at 250 VAC. The 3SAT1303A2 is designed to operate in environments between -40°C to +85°C. It also features a Push-to-Test function, indicating whether the contact has opened and closed. The 3SAT1303A2 is a reliable device with an estimated mechanical life of 10 million operations.

The 3SAT1303A2 is typically used in industrial automation, HVAC applications and telecommunications relay systems. Signal relays are commonly used in applications where it is necessary to switch between multiple viewpoints, such as in a camera system or a switchboard. It can also be used in power switching applications, where the load needs to be turned on and off quickly and reliably. The 3SAT1303A2 is also suitable for use in military and aerospace applications requiring a high reliability switch.

The 3SAT1303A2 has a number of safety features to ensure that the switch is used correctly. It has anti-vibration capabilities to reduce the effects of shock and vibration on the contacts, and protected or blocked terminals to reduce the risk of accidental short-circuits. The safety features also include a temperature limit switch set at a maximum operating temperature, which will automatically shut off the current if the temperature of the contact exceeds a certain limit.

The 3SAT1303A2 is a versatile and reliable signal relay that can be used in a variety of applications. Its low-power design makes it an ideal choice for applications requiring an economical, space-saving alternative to traditional electromechanical switching. Its wide variety of designs and contact ratings make it suitable for a wide range of applications, from industrial automation to HVAC applications and military and aerospace systems. Its safety features make it an ideal choice for ensuring the safe operation of the system.
