BA651 strain gage amplifier in din rail mount housing description the BA651 is a instrumentation amplifier in rail mount housing according to din 50022-35. it is designed to provide a low drift signal conditioning for full bridge strain gage sensors. the 10v analog output is fully bi-directional. a internal voltage reference provides the excitation for a 350 ohms sensor. an optional version to connect up to four parallel 350 ohms sensors is available. the BA651 requires a basic 19 to 28 vdc power supply. the zero and span adjustment is performed by a zero and span potentiometer with a wide adjustment range. ba 651 features: ? bi-directional output (voltage version only) ? 19 to 28 vdc power ? wide range span adjustment ? wide range zero adjustment ? din-rail mount
