Conditioners boast instrument class performance
New from Impulse Corp is the Dataforth SensorLex 8B series of isolated analogue signal conditioners
Developed in response to customer requests worldwide for a smaller, lower cost isolated signal conditioner, the SensorLex 8B more than meets the need, providing instrument class performance in a package 20% the size of competing modular products. In fact, given its high performance, low cost, and small size, Dataforth's new 8B family represents a true technological breakthrough.

The small size is ideally suited for embedded or portable applications such as mobile test stands, COTS military and defence applications, miniaturised security and surveillance systems, embedded process controls for semiconductor manufacturing equipment, and any other embedded industrial data acquisition system.
With the SensorLex 8B, it is now possible to incorporate high-performance modular I/O on a per-channel basis for any embedded monitoring or measurement and control system; in addition, because the 8B provides an Instrument Class analogue output, it makes interfacing to almost any PC/104, VMEbus, or proprietary data acquisition system board very easy.
The 8B line of miniature isolated analogue signal conditioners provides 15 family groups with a total of 95 models that interface to a wide variety of voltage, current, temperature, position, frequency and strain measuring devices.
Housed in a solidly potted thermoplastic plug-in-the-panel package measuring only 28.1 x 41.9 x 10.2mm, the 8B's industrial enclosure provides excellent impact properties, dimensional stability over temperature, chemical resistance, and a flammability rating of UL94V0.
Design-in accessories include a selection of backpanels (2, 4, 8 and 16 channels) that provide screw-terminal inputs and outputs as well as a DB25 header connector.

The DB25 header can be matched with a 1, 2 or 7m cable to connect sensors and transducers to an external 25 screw-terminal interface board.
Moreover, a power supply module in the same 8B form-factor is offered to accommodate input voltages of 12 to 36V DC and provide 5V DC output at 2A to power any combination of 8B signal conditioners.
The 8BPWR module plugs into its own socket on the backpanel, which protects the power supply module from transients and reverse wiring errors.
The 8B's fully functional Instrument Class performance provides superior specifications such as (0.05% accuracy (includes nonlinearity, hysteresis and repeatability), (0.02% linearity, three-pole filtering, 1500V RMS isolation, and low output noise.
The 8B CAN interface to a broad spectrum of analogue signals, including volt, milliamp, thermocouple, RTD, potentiometer, slidewire, strain gauge, frequency and two-wire transmitter.
Available analogue output modules provide a wide selection of current and voltage output ranges.
Each 8B module isolates the field-side input or output signal with an optical isolation barrier rated at 1500V RMS.
Common-mode rejection is 120dB; by incorporating a three-pole filter, normal-mode rejection is 70dB at 60Hz.
Operation and storage temperature is -40 to +85C, and relative humidity range is zero to 95% noncondensing.
All models meet the requirements of EN61000-6-4 (radiated/conducted emissions) and EN61000-6-2 (ESD/RF/EFT immunity).
Prices for 8B modules start at just GBP 49 plus VAT.
