Signal relays are an electronically operated switch that allows the flow of one circuit to be interrupted and controlled by another circuit while providing isolation between the two circuits. The UB2-5SNUN-L signal relay is an example of these types of relays that is designed to be used in a range of control applications. In this article, we will look at the application field and working principle of the UB2-5SNUN-L signal relay.

The UB2-5SNUN-L signal relay is a type of single-pole double-throw (SPDT) relay that is rated at 2 amps with a trip current of 5 Amps. This relay is designed to be used in general control applications and is suitable for most low-voltage and low-power electronic devices. It can be used to switch, control, operate, and protect circuits. Its construction features a thermal plastic moulded case with a double-sided design that provides electrical insulation and protection from environmental factors. The relays also feature an LED indicator to assist with troubleshooting. The contact resistances of the UB2-5SNUN-L is 30 milliohms maximum for the normally open contact, and 25 milliohms maximum for the normally closed contact.

The working principle of the UB2-5SNUN-L is simple and effective. The SPDT design of this relay allows for the outputs to be switched between two states. When the control voltage is applied to the relay coil, it creates an electromagnetic field which operates the single internal pole to switch the outputs to their desired state. This switching action is done with no physical contact between the relay and the circuit being controlled. The resultant effect of this is extended heater life, improved device safety, and less noise due to the lack of physical contact.

The UB2-5SNUN-L signal relay is suitable for use in a range of control applications, and can be used as part of an interface for a variety of different systems. It can also be used in motor control circuits, switching circuits, heating and cooling systems, appliances, and emergency lighting. Its SPDT design allows it to be used to control a variety of items, from thermostats to electric motors and small lamps.

In conclusion, the UB2-5SNUN-L signal relay is a type of SPDT relay that is suitable for use in a range of control applications. This relay is rated at 2 amps, with a trip current of 5 amps. It features a thermal plastic moulded case with double-sided insulation and a LED indicator to assist with troubleshooting. The relay works by using an electromagnetic field to operate the single internal pole, which allows for the outputs to be switched between two states with no physical contact between the relay and the circuit. This means extended heater life, improved device safety, and less noise. The UB2-5SNUN-L relay is suitable for use in motor control circuits, switching circuits, heating and cooling systems, appliances, and emergency lighting.
