TXD2SA-L-12V-3

TXD2SA-L-12V-3 is a type of signal relays, which can transmit low-level signals with 2A or less current. It is an important electronic component for controlling current and features small size, high reliability and long service life. This article will discuss the application fields and working principles of TXD2SA-L-12V-3.

TXD2SA-L-12V-3 is a capable signal relay signal, which is able to switch low-level DC and AC signals with a capacity of up to 2A. As a result, the product is suitable for use in fields like HVAC, household appliances, office electrical systems, automotive accessory equipment, and fire alarm systems. It is also commonly used in communicational electronics, such as fax machine, telephone, intercom, and broadcasting systems.

The working principle of TXD2SA-L-12V-3 is quite easy to understand. A coil is located inside the signal relay, and when the coil is given the right current level, a magnetic field is generated, which carries a metal bar to the right position. This completes a circuit in order to control the current according to corresponding instruction from user, thus relaying the signal.

The typical working process of TXD2SA-L-12V-3 can be described in detail as follows. First of all, the coil is given a proper voltage level, which creates a magnetic field around it. As the magnetic field is strong enough, the iron bar inside the signal relay will be attracted towards the magnet, thus making contact between the normally open poles and normal close poles. This turning-on phase of the switch completes a closed circuit. When the voltage is decreasing, the iron core relaxes, so the contact between the normal open poles and normal close poles will break, thus forming an open-forward circuit. This de-energizing process of the device is called the switch-off phase.

TXD2SA-L-12V-3 is an essential electronic device used for current and signal control. It features small size, high reliability and long service life, which makes it ideal for use in many fields. The product embodies the simple working principle of utilizing a coil to create a magnetic field, which is able to turn on and turn off in order to provide indispensable signal relaying service.
