DIN-rail-mount smart LVDT signal conditioner
Engineered to work with the widest range of AC-LVDTs and inductive half-bridge LVRTs, the S1A module offers a choice of 4 excitation frequencies and 8 analog outputs, operates LVDT sensors with over a 40 dB dynamic range of AC output, indicates most common system failures, and incorporates a 2-wire RS-485 digital communications port.
Thanks to the unit’s built-in digital address for RS485 communication capability, it can be used to maintain the full redundancy of multiple LVDT systems. If the “master” were to fail, another “master” having a different digital address would instantly come on stream to maintain a single excitation frequency. In this approach the only thing lost in a “master” oscillator failure is the former master channel itself. For multiple channel LVDT systems, the integrity of the output signals from the other channels is fully maintained. This “auto-mastering” feature is unique to the Alliance Sensors S1A and its variants.
