S2A Signal Conditioner

Alliance Sensors Group’s model S2A DIN rail-mounting LVDT signal conditioner is designed specifically for the power generation industry. It offers comprehensive diagnostics for sensor and wiring failure, real-time recalibration of the full scale and zero outputs, enhanced ground loop noise rejection, and backward compatibility to legacy S1A signal conditioners. Utilizing front panel push buttons for easy calibration, the S2A is engineered to work with the widest range of LVDT, RVDT, and inductive half-bridge LVRT sensors by providing four excitation frequencies that will operate most AC-LVDTs over a 50 mV_RMS to 5,000 mV_RMS range of sensor output. S2A modules offer a choice of eight analog outputs and half-duplex RS-485 digital communications to facilitate remote setup and for saving a module’s setup parameters to hot swap them with another module.
