Gebildet 2pcs DC 5V 2 Channel Relay Module Board Shield with Optocoupler Isolation Support High or Low Level Compatible Development Board Trigger

Product description

• This Relay Board Maximum load: AC 250V/10A, DC 30V/10A With power and relay action indicator.each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground
• Main Specification Peak Load of NO Connector: AC 250V/10A, DC 30V/10A; Trigger Current: 5mA; The Module Operating Voltage:5V.
• These Relay Board use photocoupler isolation that has strong driving ability and stable performance.The isolation circuit prevent damages to I / O port by relay switch current.The module has a jumper so you can set rather the unit state changes with high or low signal. Has screw terminals for relay (NC,C,NO) and for input; Coil +, coil - and trigger.
• Using SMD optocoupler isolation, strong driving capability, stable performance.Fault tolerant design, even if the control line is broken, the relay will not operate; And interface design humanized, all the interface can be directly connected through the terminal lead, so convenient.
• Wide Application These 5V relay board works well with for ARM /PIC /AVR /MCU/Raspberry/CNC machine /etc.
