Details of SG1-AA040-A1 Single Phase Input 80-280VAC Output 24-280VAC Current 40A Zero C

SG1-AA040-A1 Single phase input 80-280VAC output 24-280VAC current 40A Zero C solid state relay (Input AC, Output AC) – Operating principle and features The operating principle of the Solid State Relay with Input AC and Output AC is to control the switching of AC loads using an AC control signal.

Main Components

• Input AC (e.g., 90–280VAC): Receives AC control signals
• Opto-Isolator: Separates the control signal from the power section for safety
• Trigger Circuit: When a control signal is received, it triggers the drive circuit to activate the power section
• Output AC (e.g., 24–480VAC): Controls the delivery of current to loads such as heaters, motors, and lamps, etc.

Type Input Voltage Control AC (e.g. 90-280VAC)

• Output Type: Alternating Current Load (AC Load: 24–480VAC or 24–240VAC depending on the model)
• Frequency: 50/60Hz
• Loading Capacity: Typically supports loads from 2A to 100A (depending on the model and Heat Sink)
• Cooling Requirement: Must use a Heat Sink or fan in case of high current load
• Isolation: Prevents signal interference and enhances installation safety, usually DIN Rail or mounting plate type
• Response Time: Approximately 1–2 milliseconds

Advantages

• No moving parts – No wear and tear
• Silent operation
• Durable against vibration and dust
• Precise and quick load control
• Long service life

Cautions

• Select the SSR appropriately for the load and operating voltage
• Avoid leakage current that may occur when the SSR is in the "off" state
• Temperature: Proper cooling must be ensured, otherwise the device may get damaged
• Control electric heaters in oven systems, lighting systems, industrial machinery systems, automatic temperature control systems, motor control systems (load not exceeding specified capacity)
