7I47S 1
GENERAL
DESCRIPTION
The 7I47S is a 12 input, 8 output RS-422 interfface for Mesa’s Anything I/O series
of FPGA interface cards. The 7I47 has 12 receive and 8 transmit channels plus a analog
output intended for spindle speed control. The 7I47S is mainly intended for motion oriented
applications, for example as an output buffer and line receiver for connecting step and
direction drives and encoders to Anything I/O FPGA cards.
The controller connection is a 50 pin header that matches the pinout of Mesa’s
Anything I/O cards. All RS-422 interface connections use pluggable Phoenix compatible
3.5 mm screw terminals.
