Description12V 8 Channel Red Color Relay Module 8 Channel 12V Relay Module with Optocoupler Isolation Supports High and Low Level Trigger Red VersionProduct Features: 1. The use of genuine high-quality relay 2. Optocoupler isolation, drive ability, stable performance 3. Multi-operating voltage optional, multi-output optional 4. High and low starting mode can be set 5. Power supply, work dual indicator light 6. Input and output terminals for easy wiringProduct pin definition and function: 1. DC : positive power supply (according to the relay operating voltage selection) 2. DC-: power supply ground 3. IN or INX: control signal input 4. NO or NOX: load access, normally open 5. COM or COMX: load access, common 6. NC or NCX: Load access, normally closedTrigger Mode Configuration Description:The module has a trigger level selection terminal, each relay trigger level can be individually controlled, through the short-circuit cap to control. COM side is common, in the middle; When the LOW (L) terminal is connected to the common terminal, it is a low level trigger; when the HIGH (H) terminal is connected to the common terminal, it is a high level trigger.
