You can program and control this relay board via a PC Serial Port. Simply connect a serial cable from your computer to the connector on relay board. There are 8 relays each capable of switching 250V/12A switched by using Dinkle connectors (250V rated). There are also 4 optically isolated inputs that can be used for feed back. We provide Windows 9x/2000/ME/XP software download to control the unit. The kit is a boon to the Science Fair project, laboratory experimenter and so on. Uses serial port so it can be located over 100 yards from the PC.
