1 relay board
This board is designed to control a relay via a low intensity switching signal (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 an optocoupler for driving the relays.
