24V 1 Channel Relay Module with Optocoupler Low-Level Trigger Expansion Board 

Module 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 convenient
8. 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 relay
Relay outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays
3. NC: normally closed relay interface
High and low-level trigger options:
It is low-level trigger when jumper connects to LOW pin
It is high-level trigger when jumper connect to HIGH pin
