LVDT Signal Conditioner DIN Rail Mounted SC-100

Specifically Designed and Engineered for Automation Measurement Systems and General Industrial Applications

AC-LVDT Signal Conditioner with 2 Point Calibration

The LVDT Signal Conditioner SC-100 DIN rail module from the Alliance Sensors Group ends the usual difficulties that accompany AC-LVDT set up with a built-in null indicator and simple front panel pushbuttons to set zero and full scale. Engineered to work with the widest range of AC-LVDTs and inductive half-bridges, the SC-100 module monitors LVDT operation and indicates most common failures.

Features:

Smart setup with 2 front panel push buttons --- NO POTS Built-in null indicator: LEDs and separate DC null voltage output Choice of 2.5, 5, 7.5 or 10 kHz nominal excitation frequencies Use with 3-, 4-, 5-, or 6-wire LVDTs and inductive half-bridges Choice of 6 DC voltage outputs and 2 current loop outputs 40 dB range of FS outputs from LVDT: 50 mV rms to 5 Volts rms Fail-safe master/slave syncing eliminates beat frequencies

15 - 30 Volts DC operation, 80 mA maximum operating current Self-diagnostic for LVDT winding failures or cable disconnection Independent failure warning flag via open collector output Digital communications link via RS-485 multi-drop bus with up to 16 individual module addresses Hot swappable: set-up can be saved/reloaded via RS-485 port TWO (2) YEAR warranty instead of industry standard (1) year
