Item
Description
Ground screw
Crimp one end of the grounding screw with the cold-pressed
terminal. The other end of the grounding wire is connected to the
ground, and the grounding wire is not less than 2.5mm2
Power interface
Support Dual DC12-48V or DC48V(36-72V).
Support single power input AC85-264V or DC110-370V.
Relay output
interface
Relay alarm output function; this relay is a normally open and one
normally closed relay, the middle one is the common terminal, the two
left terminals are normally open relays, and the two right two terminals
are normally closed relays. When the switch works normally, the
normally open relay is energized and closed, and the normally closed
relay is disconnected. When the system is powered down, the normally
open relay is powered off and the normally closed relay is closed. The
recommended switching load capacity of the relay is 1A (24VCD).
Ethernet RJ45 port
Supports automatic MDI/MDI-X connection. You can connect the switch
to terminal devices, servers, hubs, or other switches.
Fiber port
The 100M fiber port is a 100Base-FX full-duplex single-mode or
multi-mode fiber connector, which support single-fiber or dual- fiber
connectors, and the connector can be SC, ST or FC. The optical
fiber connectors must be used in pairs (TX and RX are a
pair).
Din-rail kit
To fix the switch.
The indicator description of the switch is shown in the following table.
