Related Information
Multi-Loop Controller -LC500

The LC500 series controller is born out of the V-Series Integrated controller platform and repackages the functionality of the Model 1000 product into a 'DIN' size controller profile. The product is available as the LC511 (analog output type) and the LC512 (pulse output type). The product can support up to 8 PID process loops, 128 Analog input points and 32 discrete I/O. Up to an additional 7 loop displays units can be connected to the main unit to display individual loop status. These units are connected via a RS485 Multi-drop network. Additional I/O modules (up to 15) are added via the RS485 Process I/O Bus.

Multi-Loop Controller LC531/LC532

Multi-Loop Controller LC531/LC532 is an instrumentation panel controller, which supports various applications with user programs. Toshiba continuously enrich the features, reliability and user friendliness. Simultaneously securing the compatibility of attachment to limited space, panel cut and depth result to the advanced features.
