n Overview
The UM33A digital indicator with Alarms employ an
easy-to-read, 14-segment large color LCD display,
along with navigation keys, thus greatly increasing the
monitoring and operating capabilities. The short depth
of the controller helps save instrument panel space.
Also supporting the CC-Link communication.

n Features
• A 14-segment, active (PV display color changing
function) color LCD display is employed.
Two five-digit, high-resolution displays are possible.
Alphabet letters can be displayed in an easy-to-read
manner. The guide display shows parameter names.
• Easy to operate
Navigation keys (SET/ENTER and Up/Down/Left/
Right arrow keys) are employed to facilitate making
settings. Alarm Functions
• 65 mm depth • Types of Alarm
