A relay allows a low-power electrical signal, such as from a microcontroller or sensor, to control a much larger current or voltage, such as required to drive a motor or light bulb. This allows a small electronic device to control a much larger one, or to isolate the low-power circuit from the high-power one. Relays are used in a wide range of applications, including automotive systems, HVAC systems, and computer power supplies.

Part Number: SLA-24VDC-SL-A, SLA-24VDC-S-L-A

Function: 24V, Relay, 1 form A, 0.9W

Package: PCB DIP Type

Description

SLA-24VDC-SL-A is 24V, 0.9W, Relay. This indicates the voltage rating for the relay coil. In this case, the relay is designed to be operated with a 24-volt direct current (DC) power supply. Relays are electrical switches that use an electromagnet to mechanically operate the switch contacts. They are commonly used in control systems to switch higher-voltage circuits using a lower-voltage control signal.

MAIN Features:

1. Up to 30A switching in SPST and 20A switching in spot arrangements.

2. Available as an open-frame relay, with a snap-on dust cover or with an immersion cleanable, plastic sealed case.

Applications:

1. Used for power switching, Electrical Heater, ventilator, Air conditioning,

2. Refrigerating, Automobile and House-hold Appliance.
