When you need to switch heavy loads, relays are a great solution for allowing your Raspberry Pi to control high voltage and current with its GPIO pins. Stackable to 8 layers, the Sequent 4-Relay card can control loads of up to 10A and 250V. Each relay has N.O. and N.C. contacts brought to pluggable terminal blocks. Up to 8 cards can be stacked on top of a single Raspberry Pi for a total of 32 relays! Note: We do not recommend makers to control wired mains voltages/devices!
