The 8B50/51 20-kHz filter bandwidth analog voltage input modules are the latest addition to the SensorLex 8B family of isolated analog signal conditioners. In addition to wide bandwidth, the modules also provide high ratings of ±0.10% accuracy and ±0.05% linearity.

Measuring only 1.11² × 1.65² × 0.4², the 8B signal conditioner is 80% smaller than similar products, making it ideal for embedded and portable applications such as mobile test stands, COTS military and defense applications, miniaturized security and surveillance systems, and embedded process controls for semiconductor manufacturing equipment. With the SensorLex 8B, it’s possible to incorporate high-performance modular I/O on a per-channel basis for any embedded monitoring or measurement and control system. Because the 8B provides an instrument class analog output, interfacing to almost any data acquisition system board is easy.

The 8B50/51 voltage input modules accept millivolt- and volt-level signals. They achieve signal filtering with a five-pole filter that is optimized for time and frequency response and provides 100 dB per decade of normal mode rejection above 20 kHz. One pole of the filter is on the field side of the isolation barrier for antialiasing. The other four are on the system side. Common-mode rejection is 100 dB. These modules feature a special input circuit that provides protection against accidental connection of power-line voltages up to 240 VAC continuous. They gave clamp circuits on the I/O and power terminals protect against harmful transients.

Prices for 8B modules start at $89.
