5V DC 8-Channel Relay Module with Optocoupler for Mega 1280 DSP Arm PIC AVR STM32 Raspberry Pi

8-channel 5V DC relay interface board. Each channel requires a control current of 70mA; equipped with relays capable of handling high current. 230V AC 10A, 30V DC 10AEach relay has one normally open and one normally closed contact. Can be selected by a jumper and connected to +1 TTL or ground.With power indicator; each of the 8 channels has a status indicator. Integrated freewheeling diode to counteract coil winding.Standard interface that can be directly controlled by a microcontroller (8051, AVR, PIC, DSP, ARM, MSP430, TTL logic).The 8 channels are optically isolated, safe, reliable, and interference-free. Widely used for all MCU controls, in the industrial sector, PLC controls, home automation with 8-Channel Relay Module. 8-channel DC 5V relay module with optocoupler. • Available switching capacity of 10A despite the small size design for high-density PC board mounting technology. • UL, TUV recognized. • Plastic material selected for high temperature and better chemical solution performance. • Sealed types available. • Simple magnetic relay circuit to meet low mass production costs. • Widely used for home appliances, office machinery, audio equipment, automotive, etc. (TV receiver remote control, monitor display, high current audio equipment applications). • Product Description: • Product Name: 8-Channel Relay Module; Output Channels: 8Power Supply: 5V; Load Voltage: AC 250V 10A, DC 30V 10AOverall Size: 137 mm x 56 mm x 17 mm / 5.4" x 2.2" x 0.7" (L * W * H);Mounting Hole Size: 3mm / 0.12"Mounting Hole Center Distance: 132 x 50 mm / 5.2" x 2" (L * W);Material: Electrical ComponentsWeight: 122g;Package Contents: 1 x 8-Channel Relay Module
