ST-DLVA Series

ST-DLVA Series - Complete Linear DC to LVDT RVDT Converters on PCB with Mounting Track having Screw-Terminal Block for ease of wiring. 2 or 3-4 wire output configurations, Isolated Reference & Signals, 3V and 5V logic Compatible


The SLVT Series are complete, low profile, continuously updating, single channel, Isolated Digital to LVDT Converters used to simulate the output of LVDT's (Linear velocity displacement transducers), RVDT's (Rotary...) and other phase/voltage sensitive AC devices. They provide a very precise linear AC voltage output proportionate to the magnitude of the input data, in or out of phase respective of the AC reference input as determined by the MSB of the input word (offset binary format).

These converters are complete full functioning devices that require no trimming, padding components, or signal conditioning. They provide a high drive capability of up to 2000 ohms, real-world voltage reference inputs, frequencies, and signal output levels.

All units feature completely Transformer Isolated Reference Inputs and Signal Outputs, to eliminate ground loops, differing potentials, and to keep any high voltage transients from affecting the computer bus backplane, while assuring no interference with or between any devices the signals are connected to.

The SLVT series feature virtually indestructible short-circuit proof outputs, overcurrent, short circuit protection, and automatic thermal cutoff.

The output is crisp, continuous, monotonic, extremely stable, linear and precisely repeatable with very low ripple content. Because no switching or multiplexing is utilized; the output requires no additional filtering and does introduce or exhibit second frequency harmonics.

Standard units are provided with a two wire transformer output, center-tapped transformer outputs may be selected by adding a "-CT" to the end of the model number.

The gradient of the output is reflected as the output voltage/8192 for the out of phase range (negative displacement), and voltage/8192 +8192, for the in-phase range. (+, or positive displacement). The sum of the in-phase and out-of-phase ranges provide the total 14 Bit resolution. The data is MSB aligned.


Terminations subject to converter module features where applicable.

Plastic backplane mount track included, or may be mounted using spacers at mounting hole locations.
