S.Module 16-100

The S.Module 16-100 is a small size data acquisition board, providing four independent and complete analog input channels and four independent analog output channels.

Analog Input Channels
The S.Module 16-100 has 4 differential ended analog inputs. Analog inputs digitized to 16 bits at sample rates up to 100 kHz per channel.
The input voltage range can be set by software to 10.0 V, 5.0 V or 2.5 V. All input channels are protected against electro static discharge and overload up to 1.5 kV.
The filter of each channel is of 4th order and has Butterworth characteristics. The cut-off frequency of the input filter can be set by the software within the range from 100 Hz to 50 kHz. These filters are time-continuous filters

Analog Output Channels
The module also includes four single ended analog output channels with maximum update rates of 100 kHz. The output voltage range is 2.5 V.
A two-pole low-pass filter with Butterworth characteristics is provided as a reconstruction filter for each of the 16-bit D/A converter lines. The cut-off frequency can be set by the software within the range from 100 Hz to 50 kHz.

miniBus Interface
The S.Module 16-100 has a 3.3 V (5 V tolerant) digital interface to controllers/processors, fully compatible with the miniBus interface.This interface contains only a 16 bit data and a 6 bit address bus, an I/O enable, a read, a write and two interrupt lines. This enables simple connection to signal processing boards in the S.Module, D.Module and miniKit series without additional hardware, as well as simple integration with other processors/controllers.
