产品详情资料
电缆和总线终端RS485•如果需要大传输距离和大传输速度,应使用屏蔽双绞线。互电容不得超过52.5 pF/m,电缆面积应至少为0.25 mm2(AWG 24)0 V,通信参考电压应包含在布线中。双向通信使用两对;一对用于通信,一对用于0V。屏蔽必须在一端接地。另一端通常接地,但距离较长或接地电位存在差异时,屏蔽应通过0.1µF/250 V塑料电容器接地,以防止编织屏蔽中的接地电流。许多制造商建议屏蔽在每个节点处接地。不同的制造商有不同的总线终端系统。42 3BSE069463-600 D版第7节附加安装提示电缆和总线终端RS485根据接收者的设计,总线导线可能处于同一水平或需要上拉或下拉,以确保总线处于静止模式时未检测到故障信号Cable and Bus Termination RS485 • If maximum transfer distance and maximum transfer speed is needed, shielded and twisted pair cable should be used. The mutual capacitance may not exceed 52.5 pF/m, and the cable area should be at least 0.25 mm2 (AWG 24). • 0 V, the reference voltage for communication should be included in the cabling. With two-way communication use two pairs; one pair for communication and one pair for 0 V. • The shield must be grounded at one end. The other end is usually grounded, but with longer distances or when there is a difference in the ground potential, the shield should be connected to the ground via 0.1 µF/250 V plastic capacitor to prevent ground current in the braided shield. A number of manufacturers recommend that the shield be grounded at each node. Various manufacturers have different systems for bus termination. 42 3BSE069463-600 Rev D Section 7 Additional Installation Tips Cable and Bus Termination RS485 Depending on the recipients’ design, the bus wires may be on the same level or require pull-up or pull-down to ensure that no faulty signals are detected when the bus is in resting mode
