The D/3® USB Keyboard is an environmentally
hardened operator’s keyboard with keys dedicat-
ed to process control functions. It communicates

an OCM, DCM or CDCM.

The D/3 Keyboard contains an audible alarm
horn with an adjustable volume control and an
alarm relay consisting of a single set of Form C

D/3 control and display functions can be pro-
tected by limiting access to them. To access a

however, a wash down version of the keyboard is
available by special order.

Power for the keyboard functions is provided
from the USB connection. The universal 12 VDC

Dedicated Keys

The D/3 USB Keyboard simplifies operator tasks
by providing dedicated keys, grouped into a logi-
cal arrangement for operators, for selection and
process control.

There are 16 quick-select keys which are used
to select faceplates and parameters from vari-
ous OCM displays. Six keys dedicated to alarms
are used to acknowledge alarms, silence audible
alarms, and review alarms. Ten display function
keys perform general operations for viewing and
editing of displays. Eight sequence logic keys are
used for interacting with units, recipes, and mes-
sages. Five continuous control keys allow direct
access for changing setpoints, outputs, and other
functions. Finally, four keys provide functions for
modifying parameters and four keys are used to
ramp values.

See Operator Console User’s Guide for additional
information about the D/3 Keyboard functions.
