5V 1 Channel Relay Module Low Level Trigger Relay Board for Arduino ARM PIC AVR MCU with LED Indicator Light

Module description:
1. the module can be high or low by a jumper setting trigger;
2. fault-tolerant design, even if the control line is broken, the relay will not operate;
3. the power indicator (green), the relay status indicator (red)
4. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient
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 connect to LOW pin
It is high level trigger when jumper connect to HIGH pin

Package Include:
1pc relay module
