• Module Connections: 
• Control Input:
  DC +: 12V DC positive power
  DC-: 0V GND DC negative power
  CH1: input detected port, high level effective.
  CH2: input detected port, high level effective. 
• Relay Outputs:
  NO: relay normally open port, relay pull in before as the vacant,after pull in with the COM1 short connection.
  COM: relay common port.
  NC: relay normally closed port, relay with COM1 short connection before pull in, vacant after pull in. 
• Load capacity: normally open port maximum load capacity: DC 0-30V / 10A, AC 0-250V / 10A. 
• Normally closed port maximum load capacity: DC 0-28V / 10A, AC 0-125V / 10A
