12V 4-Channel Relay Board Module Active Low

Active low relay board with 12V 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 1.5V 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.

* 4 Channel * Maximum switching voltage: 250VAC / 30VDC * Maximum switching current: 10A * Module operating voltage: 12V * Each relay features an LED indicator * Dimensions: 76 x 56 x 18mm (Length x Width x Height)
