8 Channel Relay Board, Optically Isolated, High/Low inputs

Ever need a stack of relays for a project? Here's 8 of them!

These are perfect relays for any 5V logic. Input lines are optically isolated and can be driven with 5mA of current. These are designed to be fault-tolerant: even if the control line is broken, the relay will not engage. Indicator lights allow you to know the status of each relay at a glance. Each relay can be jumper selected for either high or low-level input, making them completely configurable!
