  • Maximum switching current:
    • Resistive load: 10A (240V AC) or 10A (30V DC)
  • Number of channels: 16
  • Control: Low-active (relay switches on at a low signal voltage and off at a high signal voltage)
• Voltage converter:
  • Input voltage: 12V DC (via VCC pin)
  • Output voltage: 5V DC (via 5V pin)
  • Maximum output current: 2A

• Dimensions PCB: 180 x 90mm

Package contents:

• 1x 12V Relay 16-Channel Low-Active

*Note: Due to the PCB design, the two relays on the side of the voltage converter and the rest of the circuit are not suitable for 250V AC, use a maximum switching voltage of 30V here.
