• Maximum load: AC 250V/10A, DC30V/10A
• SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA
• the module voltage 5V
• each channel module can be set high or low triggered by jumper
• Fault-tolerant design, even if the control line is broken, the relay will not operate
• Power indicator (green), 4 relay state indicator (red)
• Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
• Module size: 73 x 50 x 18.5mm (L x W x H)
• Has 4 mounting bolts holes, hole 3.1mm, spacing 67mm x 44.5mm

Interface :

• DC +: positive power supply (12V)
• DC-: negative power connection
• IN1: 1 channel signal to trigger the end , you can set a high or low level control relay
• IN2: 2 -channel signal to trigger the end , you can set a high or low level control relay

Outputs :

• NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1
• COM1: 1 relay common interface
• NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
• NO2: 2 -way normally open relay interface, the relay before floating , pull back and COM2 short
• COM2: 2 Common Interface relay
• NC2: 2 -way normally closed relay interface relay short front and COM2 , pull vacant post
