The DS-3000 Load Cell Display and controller allows you to display the data from a Digital USB Load Cell on a red LED dsiplay and allows the user to control two relays that can be programmed to either close or open at user settable weight or force levels. You can control devices such as lamps, motors, solenoids or other device to build things like a fill and pack solution or a bagging solution that allows you to fill a pound of coffee beans in a bag and then when the 1 lb weight is reached in the bad, stop the valve from fillig any more and start the thermal sealer to seal the bag.
