7I47S

Description

Manual

The 7I47S is a 12 input, 8 output  RS-422 interface for Mesa’s Anything I/O series of FPGA interface cards. The 7I47S is designed for motion control applications, both for buffering FPGA outputs and for conditioning RS-422 inputs.  In addition the 7I47S has an isolated potentiometer type analog output.  This analog output can be used for spindle speed control applications.  Three opto isolated outputs are also available.  One is intended for direction, one for enable, and one for general purpose use.  The RS-422 outputs can be used as single ended outputs for driving ground or +5V referenced loads.  When used as single ended outputs, the 7I47 outputs swing from 0 to 5V and will sink or source 20mA.  12 LEDS monitor encoder input status.  The 7I47 can also supply 5V power to encoders.  The analog output range is determined by the user supplied analog reference.  The analog output reference can be from 5 to 15 VDC.  The controller connection is a 50 pin header that matches the pinout of Mesa’a Anything I/O cards.  All buffered I/O is terminated with 3.5 mm pluggable screw terminals (supplied).
