Gebildet DC 12V 4 Channel Relay Module Board Shield Support High or Low Level Compatible Development Board Trigger with Optocoupler Isolation

Product description Size:4 Channel Specifications: Voltage: DC 12V Working Current: 65mA Trigger Current: 3mA Load Current: 10A max Single Socket Length: 7.5mm Response Time: <20ms The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA The module voltage 12V The module can be set high or low triggered by jumper Fault-tolerant design, even if the control line is broken, the relay will not operate Power indicator (green), relay state indicator (red) Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient Power Interface： DC +: positive power supply (voltage by relay requirements, 5V.9V.12V and 24V selection) DC-: negative one IN: can be high or low level control relay Load Interface: NO: normally open relay interfaces, relay before hanging, pull back and COM short-circuited COM: Relay Common Interface NC: normally closed relay interfaces, relay and COM short-circuited before, after the pull-vacan Package including: 1 x DC 12v 4 Channel Module Board

• Main Specification Peak Load of NO Connector: AC 250V/10A, DC 30V/10A; Trigger Current: 5mA; The Module Operating Voltage:12V.
• 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
• 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.
• 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.
• Wide Application These 12V relay board works well with for ARM /PIC /AVR /MCU/Raspberry/CNC machine /etc.
