Group3 Control 
 
Device Interface (DI) Enclosures come in two different versions; the CN1 and the CN3. The CN1 will accept only one I/O board, while the CN3 will accept up to three I/O boards. Both include a processor board to handle communications, error detection & correction, and diagnostics.

An RS-232 diagnostic port allows local monitoring and control of the installed I/O boards.

All DIs require 12-28 volts, AC or DC.


Please refer to the I/O Boards page for specifications on the I/O boards.


 
 
 
 
The CNA is a rugged,small, and low-cost replacement for a CN1 with an 'A' type plug-in board installed.

The analog inputs are user selectable for the choice of voltage levels, and may be digitally filtered.

The CNA has an RS-232 diagnostic port that allows local monitoring and control, a built-in signal conditioner so a separate SC is not required. It also includes PID control in firmware.

The CNA requires 18-36V DC or 14-26Vrms AC
