DCE’s CDR-IOE Multifunction I/O module is ideal for small to medium size industrial

automation projects utilizing industry standard analog, digital, or pulse sensors, and

requiring industrial rated output control to manage anything from indicator lamps to

motor start/stop operations.

The CDR-IOE is a 16 pin multifunction I/O module consisting of 8 open collector

outputs, and 8 multifunction inputs, all of which can be configured for analog, digital,

or pulse operation under software control. Data communications between the CDRIOE

and the Automation Controller is provided by a 2-wire RS485 connection.

Connections are provided to daisy chain both the RS485 and power circuits for

expansion. A passive termination is switch selectable for the last unit in the RS485

string, and dipswitch controlled pull up resistors on the inputs are standard.
