Compact Design. Space-saving, all-in-one design
In response to demand for a smaller control device, we’ve now integrated the control and operation functions into the display itself. In short, we’ve combined lamps, meter graphs, and other display devices with switches, buttons and other operation functions together in an integrated, compact PLC. In addition to reducing wire consumption and saving space, this design minimizes the number of electric parts, thus ensuring a long service life.
Powerful Functions. I/O (DIO) interfaces + special I/Os are provided as standard equipment. This provides the ability to control speed and positioning.
This compact unit is provided with standard I/Os that can function as special I/Os.* We have provided advanced control of high/low pulses up to 65kHz and high-speed counters up to 100kHz. The powerful I/O interface supports not only equipment requiring switches and lamps but also sophisticated equipment requiring advanced positioning.
*Accommodates a maximum of four I/Os.
Data Handling. Easy data gathering through an abundance of interfaces
All our models are equipped with a USB (host) interface. As a result, USB thumb drives can be used for easy collection and transmission of screen data and production data. In addition, the LT-3300 is equipped with an Ethernet interface that enables real-time collection and management of production data by using the Pro-Server EX.
Full Graphical Capability. Displays high-resolution images. Choose either a color or monochrome display.
This unit incorporates a full graphics capability that can display text and beautiful images even on a small screen. Choose either an STN color display or a monochrome (amber/red switchable) display to suit your specific needs.

Expandable Design. 13 types of EX modules are available. This increases the number of functions available with modules.
Our 13 types of varied EX Modules — ranging from analog input/output to thermocouple input — allow for easier configuration.* To expand or add functions to your equipment, simply add the modules you need, as expansion units are readily supported.
*The 5.7-inch model allows for a maximum of three expansion units. The 3.8-inch model allows for a maximum of two expansion units.
For details regarding analog modules, input modules, output modules, mixed input & output modules, and other units, please refer to the EX Module list.
Easy Operation. You can easily build and edit ladder programs and create screen images by using the GP-Pro.This capability results in reduced development requirements.
We have enabled communication between screen parts and ladder programs for easy creation of screen images. A simple drag-and-drop operation between the parts and the instruction commands greatly simplify screen creation. One software program meets the demand for freedom of control, operation, and display. What’s more, a comprehensive debug function reduces development requirements.
