DC 12V Relay Module 8 Channel Relay Board with OPTO-Isolated High or Low Level T

• 8 Channel Relay Module Voltage : 12V; Normally Open Interfaces Maximum Load : AC 250V/10A, DC 30V/10A
• 8 Channel Relay Module 12V Comes with High-Current Relay,Trigger Current : 5mA
• 12V Relay Module is 8 Channel Isolated, Each Relay Can Individually Switch On/Off by An Opto-Isolated Digital Input
• Relay Module Designed With Fault-Tolerant , Even If The Control Line Breaks, The Relay Will Not Move; With Optical Coupling Isolation,Triggering More Reliable and Stable
• 8 Channel Module Equipped With Screwed Terminal Plate and Fixed Bolt Holes,Standard Interface Can Connect With Microcontrollers and be Controlled by a Wide Range of Microcontrollers

Product description Specifications:

• Working Voltage: DC 12V
• Normally Opened Compatible Load: AC 250V/10A, DC 30V/10A
• Action Time (Under Rated Voltage): Less Than 10ms
• Release Time (Under Rated Voltage): Less Than 5ms
• Power Indicator (Green), Relay Status Indicator (Red)

Input Interface:

• DC+ : Connect The Positive Pole Of The Power Supply
• DC- : Connected The Negative Pole Of The Power Supply
• IN1 - IN8 : According The Setting of Way, The Corresponding Of Relay Can Be Controlled By High or Low Level

Output Interface:

• 24 Interfaces: All Interfaces Can Be Directly Connected To Facilitate User Access
• NO1--NO8: The Relay Normally Open Interfaces,The Relay Is Suspended Before The Suction and It Is Short-Circuited With COM After The Suction
• COM1--COM8: Common Interfaces of the 8 Channel Relay
• NC1--NC8: Normally Closed Interface of Relay and It is Shorted to COM Interface Before The Suction is Closed

High and Low Trigger Selection:

• S1-S8 are the High and Low Level Trigger Selections of Relay 1 to 8 in Sequence
• COM is Shorted With Low, the Corresponding Relay is Triggered By Low Level and when COM is Shorted With High Terminal, It is Triggered by High Level
