1 ch 5V relay module with optocoupler isolation support high and low trigger

1 channel 5V Relay module with optocoupler
มีจั๊มเปอร์สามารถเลือกได้ว่าจะเป็น low หรือ high level trigger

A 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, module voltage 5V
4, the module can be set to a high level or low-level triggered by jumper;
5, fault-tolerant design, even if the control line is broken, the relay will not operate;     
6, power indicator (green), relay status indication (Red)
7, the interface design of human, all interfaces can be directly connected through the terminal leads, very
convenient 8, the module size: 50mm * 26mm * 18.5mm (L * W * H)
9, with 4 fixed Bolt hole, hole 3.1mm, spacing 44.5mm * 20.5mm

Two module interface:
1, the DC +: positive power supply (voltage relay according to requirements, 5V.9V.12V and 24V selection)
2, DC-: negative one
3, IN: can be high or low level control relay

relay Output:
1, NO: relay normally open interface, relay pull before the suspension, after the short connection with COM
2, COM: relay common interface 
3, NC: relay normally closed interface, the relay before the connection with the COM shorted, pull after the suspension

High and low trigger select side:

1. Jumper and LOW short when the trigger is low;

2. When the jumper and high shorts are high, the trigger is high.
