Product Description Chapter 2
You may integrate a power monitor into a programmable controller
based control and monitoring system by using your choice of the
native or optional communication methods.
Display Module The Bulletin 1404 display module is an optional user interface device.
The display module provides the most economical and simplest
method for setting up and configuring the master module for
operation.
The display module has a highly visible, two-line LED display and
four operator buttons with tactile feedback. Use the buttons and
display to navigate through a series of menus for configuration,
commands, and data display.
The display module is shipped with a 3 m (10 ft) long, shielded
four-pair cable that provides power and serial communication
between the master module and the display module. The display
module fits into a standard ANSI 4 in. analog meter cutout for panel
mounting. Only one display module may connect to a master module,
although you may use one display module to configure and monitor
any number of master modules one at a time.
