4 relays board
This board is designed to control four relays via low intensity switching signals (for example an LED output). The typical low-level signals, often used in TTL and CMOS digital technology, can therefore be used to switch high currents, up to 3 A at 220 V. The board is equipped with photocouplers for driving the relays. Ideal for Microcontroller systems such as Arduino, Raspberry, ELC8951, etc.
