Active low relay board with 5V relays capable of being switched on-off by an opto-isolated digital input. The relays are controlled by a microcontroller connected to the output pin and require a minimum 1V to switch the inputs ON. Suitable for 5V and 3.3V devices, these boards are perfect for Raspberry Pi, Arduino, PIC and various other microcontrollers. * 8 Channels * Maximum switching voltage: 250VAC / 30VDC * Maximum switching current: 10A * Each relay features an LED indicator * Dimensions: 138 x 56 x 18mm (Length x Width x Height) https://elecena.pl/product/27315146/5v-8-channel-relay-board-module 2024-11-21
