Uit voorraad leverbaar

Unmanaged 5-Port Industrial Ethernet Switch 

● Automatic MDI/MDI-X crossover for plug-and-play
● Each port supports both 10/100 Mbps speed auto negotiation
● Store-and-forward architecture
● Full duplex IEEE 802.3x and half duplex backpressure flow control
● Provides broadcast storm protection
● Supports 4 kV Ethernet ESD protection and 1 kV EFT protection
● Provides ESD protection 4 kV, EFT protection 3 kV and Surge protection 2 kV for power line
● Supports redundant +12 ~ 56 VDC power input
Reverse Polarity Protection
● Supports operating temperatures from -40 ~ +75 °C
● DIN-Rail Mounting

The NS-205A has 5 Ethernet Switching ports that support 10/100 Base-TX, with a 10/100M auto-negotiation feature and auto MDI/MDI-X function. It can connect 5 workstations and automatically switches the transmission speed (10 Mbps or 100 Mbps) for corresponding connections. The flow control mechanism is also negotiated. There is activity/link/data rate LEDs for each port to aid trouble-shooting. Port connectors are shielded RJ-45.It contains "soft start" function with overload protection, high-low voltage protection. The width of the NS-205A is just 33mm, so it can be used where space is important.

The NS-205A switches provide +12 ~ 48 VDC redundant power inputs that can to install a second power source to ensure the continuous operation of the    NS-205A.

The NS-205A have DIP switches for enabling or disabling broadcast storm protection, providing another level of flexibility for different industrial applications.
