5V 12V 24V high and Low Level Trigger 1 Channel Relay Module Interface Board Shield for AVR DSP ARM MCU(Blue 12v)

relayRed Relay Supports High And Low Level TriggerinThe Blue Relay Supports Low Level TriggeringModule description:1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;3. the module Operating voltage 5V 12V 24V ;4. the module can be high or low by a jumper setting trigger;5. fault-tolerant design, even if the control line is broken, the relay will not operate;6. the power indicator (green), the relay status indicator (red)7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient8. module size: 50mm*26mm*18.5mm (L*W*H)Module interface:1. DC+: positive power supply (VCC)2. DC-: negative power supply (GND)3. IN: can be high or low level control relayRelay outputs:1. NO: normally open relay interface2. COM: Common Interface Relays3. NC: normally closed relay interfaceHigh and low level trigger options:It is low level trigger when jumper connect to LOW pinIt is high level trigger when jumper connect to HIGH pin:1, The module complies with international safety standards, control area load area isolation groove;2, Genuine relay 3, With the power and relay action instructions, pull bright disconnect does not shine;4, When a signal in the signal input terminal, the common terminal and the normally start conduction;5, Microcontroller development board can be used as a module that can be used as a home appliance control;6, The control of the DC or AC signal, can control 220V AC load;7, There is a normally open and a normally closed contact;8, Blue KF301 terminals to the line of control is more convenient.Description of the high and low trigger, friends do not understand Take a look at:High level trigger is a trigger voltage between the signal input and ground can be under
