Product Description

Introduction
LK large-scale PLCs fully integrate the advantages of PLC and DCS, which feature not only standardization, integration, openness, and fast discrete control, but also powerful analog control functions. LK large-scale PLCs have got Conformité Européenne (CE) and Underwriters Laboratories (UL) certifications. In order to adapt to special environmental applications, LK large-scale PLCs adopt high-end industrial-grade chips and professional design. All modules have undergone strictly professional testing and three-proof treatment.

Features

·  Single-rack or dual-rack redundancy configuration

·  High-performance industrial-grade processor with the dominant frequency of up to 766 MHz

·  Support for a variety of communication protocols, and different types of I/O modules expanded in various ways

·  All boards coated with protective paint which is of moisture, salt spray, and mold resistance

·  High-reliability system, which features isolation, self-diagnosis and preset functions

·  Hot swapping and fool-proofing design supported by all modules

·  Operating temperature ranging from -40ºC to +70ºC and storage temperature ranging from -40ºC to +80ºC
