The Pololu basic 2-channel relay carrier modules allow simple, independent control of two single-pole, double-throw (SPDT) switches from low-voltage, low-current control signals. This item includes the basic carrier PCB along with two Omron G5LE-14-DC12 12 V relays, 5.0 mm terminal blocks, and 0.1" male headers in straight and right-angle versions. Surface-mount components are pre-assembled on the PCB, but the through-hole components are not installed. The included power relays are rated for up to 10 A under most conditions.
