The S1A AC-LVDT signal conditioner touts smart and fast LVDT setup with built-in null indication and simple front panel pushbuttons to set zero and full scale. Engineered to work with the widest range of AC-LVDTs, RVDTs and inductive half-bridge sensors including three-wire GE LVRTs and GE gas turbine LVDTs with the buck-boost, the S1A DIN rail module supports LVDT operation and indicates most common failures. It offers a choice of four excitation frequencies, eight analog dc outputs (six dc voltage and two current loop outputs) and RS-485 communications. Viable applications for the S1A module include turbine control systems, steam valve position feedback, and other types of redundant control systems that use LVDT position sensors. In the event of a failure, a new S1A DIN rail module can be hot swapped into an existing installation, with initial calibration data saved then reloaded via RS-485 port. Through the digital communications link, the S1A also can be setup remotely. For installations where there are multiple position sensors, the S1As can be master/slaved to prevent cross talk between sensor signals. Should a master fail, standard signal conditioners will revert back to their own oscillators, opening them to the cross talk the master/slave configuration was designed to prevent. If the S1A master fails, the first slave becomes the new master for the other slaves. For more information, go to http://www.alliancesensors.com/lvdt-signal-conditioner-din-rail-mounted-s1a-series.
