yinuo-link industrial 5 ports 100Mbps ethernet switch support positive and negative dc input Description: YN-IES10502 is 5 port industrial grade unmanaged Ethernet switch, it has 5*10/100Mbps self-adaption Ethernet ports. Provide DC input and positive and negative connection protection to prevent burnout. Small size design, and support industry-standard DIN Rail mounting and wall mounting, it is easy to install in any industrial environment. Advantages: 1. Using 8 Port high-temperature and low-temperature industrial-grade import chip, the processing capacity is stronger. 2. PCB using high temperature plate TG150 KB material, immersion gold process; good antioxidant capacity. 3. Crystal import from Japan Kyocera brand (the world's most famous crystal). 4. Network port using gold-plated 1.5U, conventional is 0.6-0.8u, itâ??s good for pull and plug time. 5. Import Power Supply, the largest support 12-50V. 6. All capacitors use Murata brand, the filter effect is strong stability. 7. Static support 4KV contact, power supply and network port surge support IEC61000-4-5 standard differential mode 2KV, common mode 4KV. Features: 1. Support IEEE 802.3, IEEE 802.3u, IEEE 802.3ab standard; 2. Full-duplex use IEEE 802.3x standard, half-duplex use Backpressure standard; 3. 5*10/100M self-adaption RJ45 port, all ports support auto flip (Auto MDI / MDIX) 4. Each port support auto-negotiation function, automatic adjust the transmission mode and transmission rate; 5. Support MAC address self-learning; 6. Dynamic LED indicator, to provide a simple working status tips and troubleshooting; 7. Lightning, surge, static full protection, surge differential mode 2KV, common mode 4KV. 8. Redundant dual DC power input overload protection; 9. Using industrial 3P terminal 24-36V input maximum support 50V. Power supply use US chips
