Weeder Technologies Relay Output cards with free Window's software

Using a computer to control external electrical devices requires a relay controller card. These cards can have their own built-in relays, or an open-collector output which can drive an external relay, solenoid, or other actuator. Our small low-cost relay controller cards which plug into an RS-232 or USB port of a computer provides the interface needed for relay operation, and can be used for computer controlled automation applications.
