1783-US8T 以太网非管理型交换机  该交换机使用基于包的阈值

【产品详情】

Allen-Bradley 1783-US8T Stratix 2000以太网非管理型交换机具有8个RJ45 10-100铜端口和10-100 Mbps的以太网数据速率。该交换机使用基于包的阈值，它的广播风暴阈值为每端口10 Mbps时每秒20包(pps)，每端口100 Mbps时每秒200包(pps)。也有黄色和绿色状态指示灯，闪烁频率为105mm。通过指示灯可以查看交换机的网络连接或网络活动、端口速率和电源的当前状态。它使用din导轨安装，有一个开放式的外壳，并测量5.31 x 4.19 x 2.11英寸。

对于直流电源连接，1783-US8T交换机需要0.75 ~ 2.5 mm2 (18 ~ 14awg)双绞线。功能接地线应选用2.5 mm2 (14awg)铜线，并采用合适的环形端子。电线的额定温度应高于开关外壳外的环境温度30 ËšC。

周围空气最高温度为60 ËšC, 1783-US8T的非冷凝相对湿度范围为5-95%。其工作温度为0-60 ËšC，非工作温度为-40-85 ËšC。工作振动为2g, 10- 500hz，工作冲击为15g，非工作冲击为30g。

24V AC/DC时的最大功耗为4.04 W，额定电流为361 mA。1783-US8T的最大浪涌电流为2.2 A，所需电源为24V (18-60V DC, 18-30V AC, 50- 60hz)， Class 2/SELV。该开关还具有从电源到网络通道的连续隔离电压30V，已在500V AC下进行了60秒的型式试验，属于基本绝缘类型。请注意，1783-US8T交换机在各个网络通道之间没有隔离。

【英文介绍】

The Allen-Bradley 1783-US8T Stratix 2000 Ethernet unmanaged switch features eight RJ45 10-100 copper ports and Ethernet data rates of 10-100 Mbps. The switch uses packet-based thresholds, and its broadcast storm thresholds are 20 packets per second (pps) at 10 Mbps per port and 200 packets per second (pps) at 100 Mbps per port. There are also yellow and green status indicators that blink at a frequency of 105mm. You can view the network connection or network activity of the switch, port rate, and the current status of the power supply. It is mounted using din rail, has an open housing, and measures 5.31 x 4.19 x 2.11 inches.

For DC power connections, the 1783-US8T switch requires 0.75 to 2.5 mm2 (18 to 14awg) twisted pair cables. Use 2.5 mm2 (14awg) copper wire for the functional ground cable, and use appropriate ring terminals. The rated temperature of the wire should be 30 E? C higher than the ambient temperature outside the switch housing.

The maximum ambient air temperature is 60 E? C, and the non-condensing relative humidity range of 1783-US8T is 5-95%. The operating temperature is 0-60 E? C and the non-operating temperature is -40-85 E? C. The working vibration is 2g, 10-500hz, the working shock is 15g, and the non-working shock is 30g.

The maximum power consumption at 24V AC/DC is 4.04W and the current rating is 361 mA. The 1783-US8T has A maximum surge current of 2.2 A and requires 24V (18-60V DC, 18-30V AC, 50-60hz), Class 2/SELV. The switch also has a continuous isolation voltage of 30V from the power supply to the network channel, has been type-tested for 60 seconds at 500V AC, and belongs to the basic insulation type. Note that the 1783-US8T switch is not isolated between individual network channels.
