DEVMO 8 Channel DC 5V Relay Module Board, (4PACK) Electrical Equipments 8-Ch Optocoupler Compatible with PIC AVR DSP ARM MCU PLC Smart Home Control Switch

DC 5V 8-Channel Relay Module Feature: Can be used as microcontroller development board module can be used as home appliance control 3V-5V to TTL control signal The control signal DC or AC, 220V AC load can be controlled There is a normally open and one normally closed contact A power indicator light A control indicator, pull off, disconnect does not shine Transistor drive to increase the relay coil control pins high impedance The control pin has a pull-down circuit to prevent malfunction relay vacant Product Name: 8-Channel Relay Module Output Channel: 8 Power Supply: 5V Load Voltage: up to AC 250V 10A, up to DC 30V 10A Material: Electric Part Package Content : 4x 5V 8-Channel Relay Module

• 5V 8-Channel Relay interface board, each one needs 15-20mA Driver Current; Equiped with high-current relay, AC250V 10A ; DC30V 10A.
• Each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground.
• With power indicator,8-way road has a status indicator. With a relay coil to absorb the diode protection.
• Standard interface that can be controlled directly by microcontroller (8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
• The 8 channels are optically isolated, safe, reliable, anti-interference. Widely used for all MCU control, industrial sector, PLC control, smart home control.
