This module is used when it comes to the need for isolation control and voltage conversion. br. Drive terminal signal voltage 3.6-24V. Output terminal voltage range 3.6-30V output current depends on the specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportionalbr. It can realize 3.3V or 5V to control the interface of 3.6-30V voltage . After the control terminal is turned on, the controlled terminal will also be turned on.br. Photoelectric isolation has strong anti-interference ability. It can drive high-power triodes, MOS tubes and other applications that require high-voltage driving, and can also directly drive low-power 24V relays.If it is a pulse signal, please note that the limit of 817 is 4KHZ or less. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly.br.

This Relay Board Maximum load AC 250V10A, DC 30V10A 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 250V10A, DC 30V10A Trigger Current 5mA The Module Operating Voltage12V.. 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 12V relay board works well with for ARM PIC AVR MCURaspberryCNC machine PS4 etc..
