Product Details of Solid State Relay Model : SG1-DA100-A2 Single phases Input 4-32VDC Output 48-480VAC Current 100A

Working Principle of Single Phase Solid State Relay (SSR) Model : SG1-DA100-A2 Single phases Input 4-32VDC Output 48-480VAC Current 100A

• Input DC / Output AC Working Principle
• Input (Input DC): Accepts DC voltage (e.g., 3–32VDC) to command the SSR to operate
• When DC power is applied to the input terminal → It triggers the SSR to "close" the circuit at the output terminal
• Isolation:
• Uses Opto-Isolator (PhotoCoupler) to separate the control circuit (DC) from the power circuit (AC) for safety
• Output Stage: Typically uses Triac or SCR to switch on/off AC current circuits for loads
• When input is activated → Output will "connect" allowing AC current to flow to the load General Features of SSR (Input DC / Output AC)
• Control Voltage (Input Voltage) 3–32VDC (e.g., 5VDC, 12VDC, 24VDC are applicable)

Features of Solid State Relay Model : SG1-DA100-A2 Single phases Input 4-32VDC Output 48-480VAC Current 100A
