KNACRO 4-Channel 10A Relay Module DC 24V with Optocoupler Isolation High Low Level Triger

KNACRO 4-Channel 10A Relay Module DC 24V with Optocoupler Isolation High Low Level Triger

• This module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A
• Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA
• This module can be high or low by a jumper setting trigger
• Fault-tolerant design, even if the control line is broken, the relay will not operate
