The IA-400D is a signal conditioner for iWorx-brand transducers that provides four channels of excitation power, gain, and noise filtration. It exhibits low system noise and offset, making it suitable for use with high resolution data acquisition systems.

Filters

Each channel of the IA-400D has a switch to allow selection of either a 40 Hz or 10 kHz low pass filter.? This makes the IA-400D an ideal solution for conditioning signals from low-bandwidth transducers such as those used to measure blood pressure or force as well as those applications requiring wider bandwidth.

When used with the C-ISO-256 , the IA-400D can be used to measure Biopotentials such as ECG, EMG etc. from humans.

Gain Control

Gain control on the IA-400D is very straightforward. A programming resistor in the DIN-8 connector is used to set the gain. iWorx transducers set the IA-400D gain to the optimal value for a given measurement. However, this does not limit the IA-400D to use with iWorx transducers. Many non-iWorx transducers, can be modified to work with the IA-400D.

Offset

The IA-400D is an inherently low offset device. This, together with the low offsets characteristic of bridge-style transducers and the high resolution of the iWorx data acquisition systems dramatically minimizes the need for offset control. The IA-400D user experience is simplified as a result.

The IA-400D is packaged in a low profile enclosure that provides both durability and noise immunity. The device has a small foot print measuring just 6.2 in. x 5.3 in. x 2.3 in. (17.5 cm x 13.5 cm x 6cm)and multiple units are easily stacked to save bench space.
