LCA1 Load Cell Amplifier is a device used to provide excitation voltage for a load cell and amplify low voltage load cell signal to a level suitable for 0-5V analog inputs. The LCA1 is designed to provide highly precise amplification of load cell signal for use with DC1 series dyno controllers. It can also be used with other controllers. Gain is adjusted to allow 20% load cell overload without clipping with 2mV/V load cell and DC1 controller. The amplifier is enclosed in a standard DIN rail enclosure.
