Smart Industrial AC-LVDT Signal Conditioner Module

Alliance Sensors Group’s new SC-100 DIN-rail-mounting smart LVDT signal conditioner module makes setting up and calibrating an AC-LVDT installation very easy by offering built-in null indicators and front panel pushbuttons to set zero and full scale output. Engineered to work with the widest range of LVDT and inductive half-bridge linear sensors, the SC-100 module offers a choice of 4 excitation frequencies, works over a 40 dB range of full scale sensor outputs, and features 8 analog DC outputs, including a bipolar voltage output for legacy systems. Using its 2-wire RS-485 digital communications port, a user can remotely set up and operate an SC-100 module from a personal computer, and can get information for data acquisition. The very reliable SC-100 module comes with a 2-year limited warranty and offers many additional features that make it the easiest to use and best value of any industrial single channel AC-LVDT signal conditioner currently available.

Features

Smart calibration setup with front panel push buttons --- no pots, no calculations
Built-in null indication --- front panel LEDs and DC null voltage output
2.5 kHz, 5.0 kHz, 7.5 kHz, and 10.0 kHz nominal excitation frequencies
Fail-safe excitation syncing by auto-mastering prevents cross talk in multiple units
Works with LVDT full scale outputs ranging from 50 mV to 5000 mV
Half-duplex digital communications via RS-485 2-wire multi-drop bus

Options

USB to RS485 cable

Specifications
