Analog amplification and filtering module

June 11, 2010
The Calex Model 6255 is a DIN-rail-mount, self-contained, DC-powered module designed for load-cell, strain-gage or single-ended analog amplification and filtering. It contains a precision instrumentation amplifier, filtered output and a built-in excitation supply. The 6255 provides a cost-effective solution for applications such as conveyor weighing systems, hoppers or tank farms.The 0 mV to 50-mV input range makes it compatible with most strain-gage-based load-cell or pressure-transducer outputs. The built-in 10V excitation supply is capableof driving a 350-ohm bridge. The filtered output of the 6255 is 100 Hz to 10100 Hz. Connections are made via easily accessible screw-clamp terminal blocks. Zero and Span adjustment potentiometers are located externally as well for easy access. Overall dimensions are 3.78"L x 1.06"W x 1.65"H. The 6255 is backed by Calex's five year warranty.
