Description
SLA-12VDC-SL-A is songle 12V, DC Relay. 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.
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.
