This is an isolated 8-channel 5 volt relay module. The output rating for each relay is 230 volts 10 Ampere or 10 ampere at 30 volt DC. Since each relay is provided with independent common terminal along with Normally Open (NO) and Normally Closed (NC) pins it is very easy to use. Each trigger pin is isolated from the relay using a opto-coupler thus making sure your circuit is save no matter what. 8 LED indicators are provided to display the individual Relay Status. The relays can be controlled directly by a wide range of microcontrollers such as Arduino , 8051, AVR, PIC, PLC,DSP, ARM, ARM, MSP430, TTL logic circuits, etc.

Features:

• 5V relay with AC contact capacity of 10A 250V and DC 30V 10A with optocoupler protection.
• There are 8 normally open and 8 normally closed contacts.
• Suitable for a variety of platforms such as 51/AVR/AVR/ARM.
• When the level signal is on, the common terminal and the normally open will turn on.
• Blue KF301 terminal control line is more convenient.
• Dimension: 138mm * 56mm * 18.5mm
• Net weight: 120g

Package Includes:

• 1 x 5V 8 Channel Relay Module With Optocoupler Relay Output
