*Relay coil voltage is supplied to the relay driver board through three isolated power pins. Each pin is routed to a group of four driver connectors
(6 drive lines per connector). The three coil voltage pins can be connected to the same supply voltage or to three different voltages. This provides
the flexibility to use, for instance, 24 V, 12 V, and 5 V relays all with one driver board.
