8-Channel Relay Module It is also able to control various appliances and other equipments with large current.Standard interface can be directly connected with microcontrollers. Red working status indicator lights are conducive to the safe use. 8 Channel DC 5V Relay Module with Optocoupler Feature: Can be used as microcontroller development board module can be used as home appliance control 5 V-12V 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 Specifications: Product Name: 8-Channel Relay Module Output Channel: 8 Power Supply: 5V Load Voltage: AC 250V 10A, DC 30V 10A Total Size: 137mm x 56mm x 17mm/ 5.4" x 2.2" x 0.7" (L*W*H); Mounted Hole Size: 3mm/ 0.12" Mounted Hole Center Distance: 132 x 50mm/5.2" x 2"(L*W); Material: Electric Part Package Content : 2 x 8-Channel Relay Module

Widely used for all MCU control, industrial sector, PLC control, smart home control. 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). Each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground. 5V 8-Channel Relay interface board, each one needs 15-20mA Driver Current;Relay output maximum contact is AC250V 10A and DC30V 10A.
