The TQ2SS-L2-3V-Z signal relay is designed for applications where a low-level signal triggers an electric current of up to 2 amps. It can be used to quickly and reliably switch large currents on and off in response to small control signals, allowing for accurate and safe control over electrical circuits. This relay has a number of features that make it both versatile and reliable across a range of applications.

Switching Actions

The TQ2SS-L2-3V-Z signal relay is designed for single-pole single-throw (SPST) switching actions. In this type of action, a current is either allowed to flow across the circuit or is broken. This allows for a high degree of accuracy in controlling the current, which makes it suitable for a number of establishing and breaking applications, such as switching circuits on and off.

Back EMF Protection

The TQ2SS-L2-3V-Z is also designed with back electromotive force (EMF) protection. This is a feature of any electrical circuit, and it can cause damage to the equipment in the circuit if not properly controlled. This protection feature helps to ensure the circuit is not irreversibly damaged due to EMF, making it a safer and more reliable option for use in sensitive electronic circuits.

Inrush Current Limiting

The TQ2SS-L2-3V-Z has a feature for inrush current limiting. This feature helps to limit the amount of current flowing through the circuit when it is first switched on, making it useful for applications that need to reduce the stress on the components in the circuit upon switching. This is particularly useful when the components in the circuit are of a sensitive nature, such as temperature sensors or microcontrollers.

Insulation

The TQ2SS-L2-3V-Z is designed with an insulating sheet between the coil and contact to help prevent arc damage. This helps to reduce the risk of damage to the contacts, and it helps to ensure that any arcing is contained within the insulating layer. This makes it suitable for use in a wide range of environments where the risk of electrical arc damage is an issue.

Working Principle

The working principle of the TQ2SS-L2-3V-Z relies on the passage of a current through an electromagnetic coil. This generates a magnetic field around the coil which attracts a contact arm in the relay. The passage of current through the control circuit causes the contact arm to move, thereby switching the main circuit on or off. This allows for the passage of the larger current in the main circuit to be controlled quickly and reliably by a smaller control current.

Applications

The TQ2SS-L2-3V-Z signal relay is suitable for a range of applications up to 2 amp currents. It is a suitable choice for controlling mains voltage and other large circuits, as well as for switching on indicators and alarm systems. Its insulation and back EMF protection make it suitable for use in sensitive control circuits, such as those for temperature and pressure monitoring. Additionally, its inrush current limiting makes it suitable for use in power supplies.
