1 2 4 8 Channel DC 5V Relays Module with Optocoupler Low Level Trigger Expansion Board for arduino for Raspberry Pi
Product Description
1.The module uses genuine quality relay, normally open interfaces.
2.Using SMD optocoupler isolation, driving ability, stable performance.
3.The module can be high or low by a jumper setting trigger
4.Fault-tolerant design, even if the control line is broken, the relay will not operate.
5.The power indicator (green), the relay status indicator (red)
6.The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.

Maximum load: AC 250V/10A, DC 30V/10A
Trigger current: 5mA
Working voltage: 5V
Module size: 50 x 26 x 18.5mm (L x W x H)
Four mounting bolts holes, diameter 3.1mm
DC+: positive power supply (VCC)
DC-: negative power supply (GND)
IN: can be high or low level control relay
NO: normally open relay interface

It is low level trigger when jumper connect to LOW pin
It is high level trigger when jumper connect to HIGH pin

1. The new 5V Relay Module Can be used as microcontroller development board module can be used as home appliance control
2. 5 V-12V to TTL control signal
3. The control signal DC or AC, 220V AC load can be controlled.
4. There is a normally open and one normally closed contact
5. A power indicator light
6. A control indicator, pull off, disconnect does not shine
7. Transistor drive to increase the relay coil control pins high impedance.
8. The control pin has a pull-down circuit to prevent malfunction relay vacant
