3.3.1 Non-Isolated Discrete Inputs (DI) on TB2 and TB3 of Process
I/O Board
Wiring See Figure 3-2 for wiring diagrams.
Software Configuration To use data from these DIs you must include a CWM_EIO board in

Process I/O Board terminal block connector TB2 provides interface to
four dedicated non-isolated Discrete Inputs DIs – DI1 through DI4. In
addition, terminal block connector TB3 provides two additional points
that can serve as either discrete inputs or discrete outputs (DI5 and DI6
when wired as inputs).

Configurator, and then configure it. See the ControlWave Designer
Programmer's Handbook (D5125) for more information. That same
manual includes an I/O Mapping section that describes, for advanced
users, the I/O map for this board.
You must specify whether a discrete input/output is a DI or a

Characteristics
 Supports dry contact inputs pulled
internally to 3.3 Vdc when field input is
open.
 Source current for DI1 to DI4 of either
60 μA or 2 mA based on switch SW1-
3 setting. See Table 3-1.
 Source current for DI5 to DI6 of either
200 μA or 2.2 mA based on switch
SW1-3 setting. See Table 3-1.
 15 ms input filtering
