SG1-AA25-D1 Input 80-280VAC Output DC 5-120VDC 25A TR-FET Control

Details of SG1-AA25-D1 Input 80-280VAC Output DC 5-120VDC Current 25A TR-FET Control

The SG1-AA25-D1 Input 80-280VAC Output DC 5-120VDC Current 25A TR-FET Control Solid State Relay (SSR) is an electronic device used to control the on-off switching of electrical circuits without moving parts like in electromechanical relays (EMRs), which makes it more durable and has a longer lifespan.

Features of this SSR Model

• Input: 80 – 280VAC (controlled by alternating current)
• Output: 5 – 120VDC (works with direct current loads)
• No moving parts: thus, it operates silently and has slower wear and tear
• Rapid response: can perform on-off switching very quickly (in milliseconds)
• Durable against vibrations and dust: as there are no mechanical contacts

How It Works

When alternating current voltage between 80-280V is supplied to the SSR input terminals, the internal circuit of the SSR uses an Opto-Isolator (or Opto-Coupler) to isolate the control circuit from the load circuit. The signal from the Input side triggers the transistor (or SCR/MOSFET) on the Output side to operate, and then it can supply direct current (5-120VDC) to the load connected at the Output.

Applications

This SSR model is suitable for applications that require controlling DC loads from AC control sources such as:

• Controlling DC motors or solenoids
• Factory automation systems (Factory Automation)
• Temperature control systems (Temperature Controller)
• Machinery requiring speed or DC voltage control
• Used with PLCs or Timers that have AC output
