One-Loop Controller LC500 Series
The LC500 is a series of box type controllers equipped with display functions, inputs and outputs, and a side keyboard for setting parameters.
The series is suited to general industrial and plant control systems, ranging from standalone to medium- and small-sized control systems.
"Out of production"
We appreciate your patronage towards the Multi-Loop Controller LC521/LC522, discontinued in 2013 the end of September.
The successor model is the Unified Controller nv series LC531/LC532.
Display functions and inputs and outputs integrated
The controller functions based on the loop control module (L1) is integrated with the display functions and inputs and outputs into a box type one-loop controller.
Expanded multi-loop controller functions
PID control of up to 8 loops is possible, and a display LD512H can be additionally installed for each loop. This evolution from one-loop control to multi-loop control offers easy adaptation to changes in the control range, and helps reduce total cost.
Up to 15 I/O modules can be installed apart from the controller. This means flexibility in system configuration.
Side keyboard built in
A side keyboard is built inside the controller for display and setting of control parameters and for checking alarm information. A simple change or check of parameters can be done without taking a tool computer to the control site.
Compatible with Engineering Tool 2
Engineering Tool 2 of the Integrated Controller is used for engineering. It supports the total domain of engineering, ranging from programming to online monitor of program data, status surveillance, and event log functions. By dividing a program into function blocks, reuse of the functions is made possible, thereby improving engineering efficiency.
The TOSLINE™-S20LP, Toshiba's control LAN/field network/device network, is provided as a standard feature (LC511, LC512). This permits connection to units of the Integrated Controller series or PROSEC T series to constitute a medium or small-sized control system.
