8 Channel Optocoupler Relay Board High & Low Trigger Module (5V)

[5V OPERATING VOLTAGE] Designed with a 5V working voltage to match compatible control circuits while delivering stable 8 channel relay switching for PLC automation and control board applications. [10A CONTACT RATING] Supports common interface loads up to AC 10A and DC 30V 10A giving each channel practical switching capacity for voltage monitoring expansion and automation tasks. [OPTOCOUPLER ISOLATION] Chip type optocoupler isolation provides strong driving capability stable performance and added protection between the control side and relay side with 5mA current. [HIGH LOW ] Each relay channel can be set by for high level or low level making the module easier to match different controllers and control logic requirements in use. [NO NC COM TERMINALS] Includes 24 wiring interfaces with NO NC and COM terminals for all 8 channels plus clear power and relay indicators and four mounting holes for neat secure installation.
