12V 4 Channel Relay Board Module Active Low - Terminal Blocks

4 channel 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. The modules can be controlled directly by a microcontroller and are suitable for 12V applications.
