IV. Industries Served:

6EP1334-1LB00 Power Supply

Its primary design objective. To supply power to automation components such as PLCs (programmable logic controllers), I/O modules, industrial sensors, relays, solenoid valves, and small motors. It is used in various industrial machines and instruments that require a standard 24V power supply.

It can be combined with SIMATIC buffer modules, DC UPS (uninterruptible power supplies), redundancy modules, and optional modules to further enhance the availability and reliability of the 24V power supply in critical applications.

V. Customer Case Studies:

Automation Upgrade Project for a Production Line at a Medium-Sized Steel Company in India | SIMATIC S7 Full Series PLC Application Case Study

·1 SIMATIC S7-400H redundant PLC master system (core control for the main rolling line)

·2 SIMATIC S7-1500 series PLCs (temperature control for heating furnaces, logic control for the finishing line)

·SIMATIC S7-300 Series PLC Modules: a batch (for new slave stations and on-site spare parts replacement)

SIMATIC S7-1200 Series PLCs: 5 sets (for auxiliary processes such as raw material conveyance, water treatment, and dust collection systems)

Issue 1: It is difficult to achieve synergy between the old and new systems, making unified management unfeasible.

Issue 2: Equipment reliability is insufficient under extreme operating conditions, and the failure rate remains high.
