Even if this is a normal interface for fuel pumps, there are some cases in which it is necessary to connect to the POS. Some examples are high pressure fuel pumps for different fuels or chemical companies as well as scientific labs. Different samples can be pulled through the same pump. Another situation would be when adding an external module for purifying the fuel; we can control the pump and get the purified fuel. There are different ways to approach this. One way would be to use a relay board, which is an interface for the *relay* and *motor* terminal; however, this will need a PWM controller. A cheaper and easier approach would be to use a hobby H-bridge instead. The three-phase ports can be connected in order to switch the power on and off, and use the fuel pump.
