A circuit to permit forward or backward operation of a small DC motor. The direction of rotation is determined by whether +24V is applied to VFOR or VREV. If +24V is applied to both inputs or neither, the motor shuts off.

A simple circuit of my own design to permit programmable load variations on a power supply with power supply voltage feedback to permit and/or trigger recharging cycles, with voltage datalogging capability.
