MF634 Humusoft Multifunction I/O-Card
with Incremental Encoder Inputs


The MF634 is a multifunction I/O card offering most of the functions required in process control or measurement applications. MF634 offers A/D conversion, D/A conversion, digital input, digital output, quadrature encoder input, timers, counters, PWM, pulse and frequency measurements. The card contains eight 14-bit analog input channels with simultaneous sample & hold circuit and very short conversion time, eight 14-bit analog output channels, eight digital inputs and eight digital outputs, four encoder inputs with differential line receivers and four counters/timers. Encoders and counters are 32-bit wide. MF634 has 32-bit architecture for maximum performance. Analog inputs and outputs offer bipolar ranges +/-10 V which suits most measurement and control applications.
The card is designed for standard data acquisition and control applications and optimized for use with the Real Time Toolbox for MATLAB®. Because of the small size and low power consumption MF634 can be used not only in the desktop computers but also in portable computers and notebooks with docking station.
