Signal Relays, Up to 2 Amps

DS1E-SL2-DC12V application field and working principle

Signal relays are devices designed to provide electrical isolation of a control or driving circuit from a powerful load circuit. Since signal relays have lower power outputs than industrial relays, they are limited to the safe voltage and amperage of their control circuit. The operating principle of a signal relay is based on electromagnetic waving. When a small voltage is applied to the coil of the relay, an electromagnetic torque is produced to make the armature (switch) move and realize contact.

DS1E-SL2-DC12V is a signal relay with DC 12V power output and 2 A nominal current. Being a single contact version, DS1E-SL2-DC12V can be variously used to control AC or DC signals, with particular applications for switch or signal machineries, motor starters, home appliances, office equipment, automotive systems, etc. This relay has a wide variety of pin configurations and design stays, allowing it to be conveniently integrated into a wide range of fixtures and equipment.

DS1E-SL2-DC12V is equipped with an electromagnetic switch system, consisting of an electromagnet, a switch, and an armature. When power is connected to the electromagnet, a strong magnetic torque is generated between the electromagnet and the armature. This attracts the armature and brings the switch into contact, energizing the load circuit in the process. In order to disconnect the load circuit from the control circuit, the power must be disconnected from the electromagnetic coil, thus release the magnetic torque. This releases the armature from the switch and the load is no longer powered.

DS1E-SL2-DC12V signal relay is a reliable electrical isolator for a variety of industrial and home applications, due to its robust, built-to-last functionality and design. Low power, low DC voltage and reliability make it an ideal choice for these applications.
