Features:

• Size: 25 * 34 * 25 (L * W * H) Weight: 13g
• Input Power: 5V DC (160MA)
• Input control signal voltage:
• (0-1.5V state low relay ON)
• (2.5-5V state high relay OFF)
• Voltage Current: 12.5mA
• Trigger Voltage: 0-1.5V
• Trigger Current: 2mA
• Voltage: 5V
• Quiescent Current: 0mA

Module interface: Input section: DC +: Positive power supply (by relay voltage power supply) DC-: connect power negative CH: Relay module signal to trigger the end (low to trigger effective)

NOTE: Power must be DC Voltage, voltage must be consistent with the relay voltage
