2903344 Application Field and Working Principle

Signal relays are electromechanical switches used to control a variety of electrical circuits. They’re usually found in vehicles, digital systems, and home and commercial appliances. They’re designed to switch on and off based on signal triggers from other devices, and are activated by either magnetic or electrical current.

The 2903344 is a signal relay manufactured by Conta-Clip. It’s one of a series of similar relays designed to handle low power loads up to 2 amps. It’s a single-pole single-throw (SPST) type of signal relay, designed to control a single electrical load.

Applications

The 2903344 is particularly designed to be used in low voltage DC circuits such as in automotive, home and commercial appliance, and industrial equipment applications. Its low level of power consumption and high switching speed make it ideal for controlling low-power devices and circuits.

It’s also suitable for use in environmental control systems, such as those used to monitor and adjust temperature, humidity, and pressure levels in industrial processes. Its small size makes it easy to integrate into existing systems and enables it to fit into tight spaces.

Specifications

The 2903344 has a rated voltage of 12 V DC and contact rating of 2A. It has a maximum switching capacity of 8 W and a switching frequency of 300 Hz. It also features a low resistance, low voltage drop contact, and low power consumption.

The 2903344 conforms to safety standards UL, CSA, VDE, and EN60730-1-1 and is RoHS and REACH compliant. It also features corrosion-resistant brass contacts and is available in various configurations. The standard contact arrangement is normally closed, but normally open, double-changeover, and single-changeover arrangements are also available.

Working Principle

The 2903344 is a mechanical armature-type signal relay, meaning that it uses an electromagnetically actuated mechanical armature switch to open and close the circuit. The electromagnet is energized when a current is passed through it, which in turn causes the armature switch to be sucked in and close the circuit. When the current is removed, the armature switch is released and the circuit opens.

The 2903344 is designed with a low-power consumption solenoid, which requires minimal current to operate. This means that it can be used in circuits running on low voltage power sources such as batteries or solar cells.

Conclusion

The 2903344 signal relay is a lightweight, reliable, and low-power single-pole single-throw device designed to handle loads up to 2 amps. It’s suitable for low voltage DC applications such as automotive, home and commercial appliance, and industrial equipment circuits. It features corrosion-resistant brass contacts, low resistance, low voltage drop contact, and low power consumption, and is compliant with safety standards.
