Signal Relays are electromechanical devices typically used within control circuits where it acts as a switch to allow or prevent current from flowing between two points. This type of relay is especially useful when controlling a large electric load from a relatively low voltage/current control source. The TQ2SS-L2-9V-Z is one type of signal relay, designed to work off of low power voltages as low as 9V, and draw up to 2 Amps.

On the TQ2SS-L2-9V-Z, there are two input pins: a negative input and a positive input. The negative input is usually connected to ground, while the positive terminal to the power source, usually 9V. The device is activated when a voltage is applied to the positive input, while the negative input remains grounded. When both inputs are in a high state, the relay will stay closed, allowing current to flow through the contacts.

When a voltage is applied to the positive input, it energizes the TQ2SS-L2-9V-Z relay, causing its contacts to close, making it suitable for use in controlling other electrical devices. The contacts can handle up to 2 Amps of current, which is far greater than most microcontroller pins can provide.

The relay inside the TQ2SS-L2-9V-Z is controlled via a mechanical linkage. The control module sets the contact type, which is either normally open or normally closed. In a normally open type, the contacts are open when no voltage is applied to the terminals, and closes when a voltage is applied. In a normally closed type, the contacts are closed when no voltage is applied to the terminals, and opens when a voltage is applied. The contact material is usually silver or gold and their life is typically about 1 million operations.

The TQ2SS-L2-9V-Z can be used in a variety of applications, such as motor control, automation, robotics, lighting controls, HVAC systems and audio equipment. It is also commonly used as a power switch for various electronic devices. The device is relatively inexpensive and reliable and is suitable for applications where high current is not a factor.

In summary, the TQ2SS-L2-9V-Z is a signal relay designed to work on low power sources with a voltage of 9V. It allows current to flow from one point to another when a voltage is applied across the two input pins. The relay contacts can handle up to 2 A of current, and it can be used in a variety of applications requiring reliable power switching. It is relatively inexpensive and reliable.
