Serial communication module with extra I/O for PLC use


The serial adapter option, ACC4-IO, enables the user to use any member of the Mx4 controller family outside of the computer rack as a stand-alone unit or as a serially programmable unit inside the computer. Either RS-232 or RS-485 with multi-drop capabilities can be used. The Acc4 works with Mx4 PC/AT, VME and Multibus platforms.

The ACC4-IO board provides TTL I/Os in addition to the Mx4's standard I/Os for PLC use. All I/Os are TTL and user programmable. In I/O intensive PLC applications the additional I/O card provides a modular solution to your application. Per large volume OEM request DSPCG will customize the I/Os to any number of inputs and outputs.
