Advanced Smart Industrial AC-LVDT Signal Conditioner

Alliance Sensors Group's SC-200 DIN-rail-mounting LVDT signal conditioner for industrial measuring systems, testing laboratories, and factory automation offers push buttons for fast and easy calibration of the Full Sale and Zero outputs, differiential input to minimize ground loop noise, and color-coded screw terminal plugs for quick hook up. The SC-200 is engineered to work with a very wide range of LVDT, RVDT, and inductive half-bridge (LVRT) sensors by providing four excitation frequencies that operate most AC-LVDTs over a 50 to 5,00 mVrms range of sensor output. SC-200 modules offer a choice of 8 analog outputs and half-duplex RS-485 digital comm port to faciliate remote setup and for saving a module's setup parameters to hot-swap them with another module.

The SC-200 manual and datasheet are below.
