High quality 4-channel module. Consists of eight switching relays, each of which can switch current up to 10A at 220V AC or DC 10A 30V.
The relay coils are powered from 12 volts DC, which allows it to be used in a car.
Overall dimensions 75x53mm, height with leads 20mm. Distances between the centers of the mounting holes: 70 and 46 mm. Hole diameter 3 mm.
The module contains transistor switches with optocouplers, due to which it can be connected directly to microcontrollers (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic), while providing galvanic isolation from the control circuit.
The level of the control signal (Low/High) can be selected using jumpers, with each channel independently. Relay output - one group of switching contacts (NC, NO, COM).
