24VDC 10A eFuse and Protection Circuit for Programmable Logic Controllers (PLC)
Texas Instruments
This sub system design shows an IC based implementation of over voltage: over current: reverse current: reverse polarity and miss wire protection which is more accurate: lower power and faster compared to fuses: PTCs and diodes. Programmable Logic Controller (PLC) I/O modules connected to a field power supply benefit from protection on the 24V field input connectors as power supply faults or miss wiring might damage or cause the module to not operate correctly.
Features
- Short circuit protectionOver and under voltage protectionReverse polarity protectionMiss wire and Reverse current protection Surge protection (IEC61000-4-5)This reference design is tested with HW and includes a design guide
