KJJ18 Intrinsically Safe Gigabit Network Switch for Coal Mines
Product description
KJJ18 intrinsically safe gigabit network switch for coal mines is mainly used for ring network construction, ring network expansion, and network cascading in the coal mine industry. It can be coupled with the existing ring network of the mine to connect underground industrial Ethernet intrinsically safe terminal equipment, RS485 terminal equipment and other network terminal equipment. In addition, its real-time, reliable and safe data transmission meets the requirements of industrial grade.
Features
◎ The switch is a high-performance gigabit backbone network switch, suitable for constituting a backbone network of coal mines
◎ The switch conforms to the IEEE802.3 protocol and has an Ethernet optical port and an Ethernet electrical port to support full duplex
◎ The switch has RS485 and CAN data interfaces to meet the relevant requirements of MT/T899
◎ The switch supports redundant network structures such as ring network
◎ The switch offers initialization parameter settings and power-down protections. Initialization parameters can be entered and modified via the network or programming interface
◎ The switch can be managed via a network and supports SNMP
◎ The switch supports VLAN
◎ The switch can control the flow
◎ The switch offers self-diagnosis and fault indication
◎ The switch can indicate power supply, working status, and communication status
