2 Channel Solid State Relay SSR Module

Features:

• 2 channel 2 AMP Solid State Relay board
• Control 2 loads of up to 2 amps each at 120V or 240V AC.
• Good for lighting, holiday displays, etc.
• Has been assembled, and the electrical test passed.
• Led indicator for each relay.
• Use it to control various appliances and other equipment with a large current.
• It can be controlled directly by Microcontroller
• The 2.54CM pin and blue KF301 terminal are connected to the line of control.
• Input control signal voltage:
  1. 0-0.5V the state of low-level relay OFF
  2. 0.5-3.3V Unknown State
  3. 3.3-5V high-level relay ON

Module Interface:

• DC+: connect the power supply positive (press the relay voltage power supply)
• DC-: the cathode of a power supply
• CH1: 1 relay module signal trigger end (high-level trigger effective)
• CH2: 2 relay module signal trigger end (high-level trigger effective)
