IS220PTURH1B通用燃機卡件,IS220PTURH1B英文說(shuō)明
總線(xiàn)安裝指南非屏蔽導線(xiàn)的最大外露長(cháng)度應為5cm（2in）。
為了增加保護，每個(gè)屏蔽排流線(xiàn)應使用意大利面管，防止屏蔽進(jìn)出電線(xiàn)相互接觸，或接觸信號線(xiàn)。1.將串行1連接到先前設備的串行1端子和下一個(gè)設備。
2.將串行2連接到先前設備的串行2端子和下一個(gè)設備。
3.將屏蔽連接到前面設備的屏蔽。連接屏蔽出到屏蔽下一個(gè)設備。如果牛是第一個(gè)總線(xiàn)上的設備，屏蔽可以保持未連接。如果是最后一次總線(xiàn)上的設備，屏蔽可以保持未連接。
IS220PTURH1B通用燃機卡件4、將兩根導線(xiàn)插入同一接線(xiàn)板位置時(shí)導線(xiàn)尺寸必須為0.86mm2（18AWG）或更小。兩條電線(xiàn)應大小和樣式相同。不要將絞合線(xiàn)與實(shí)心線(xiàn)混合在相同的位置。如果任一總線(xiàn)終止于NIU，則連接75、100、120或150-串行1和串行2端子之間的歐姆端接電阻器。這個(gè)建議使用套圈將每個(gè)電阻器引線(xiàn)壓接至對應的串行線(xiàn)。如果未使用套圈，則扭轉每個(gè)電阻器導線(xiàn)與相應的串行線(xiàn)焊接在一起之前將導線(xiàn)插入接線(xiàn)板。系統總線(xiàn)安裝指南適當時(shí)，串行總線(xiàn)可被視為2級電路遵循接線(xiàn)實(shí)踐。最大總線(xiàn)長(cháng)度可能會(huì )受到影響當安裝需要高壓額定CM額定值時(shí)。CM類(lèi)型可以替換CL2，但不能反之亦然。無(wú)論電纜敷設長(cháng)度如何，都不要混合使用不同阻抗的電纜。請勿在長(cháng)距離和/或嘈雜的安裝中混合電纜類(lèi)型。其他未指定阻抗的小尺寸雙絞線(xiàn)屏蔽線(xiàn)可用于使用75歐姆終端，短距離運行50英尺或更少。選擇電線(xiàn)類(lèi)型可能受到地方和國家規范及行業(yè)的限制標準。咨詢(xún)電纜制造商以確定電纜的適用于特定類(lèi)型的安裝。
Bus Installation Guidelines
The maximum exposed length of unshielded wires should be 5cm (2in).
For added protection, each shield drain wire should be insulated with
spaghetti tubing to prevent the Shield In and Shield Out wires from
touching each other, or the signal wires.
1. Connect Serial 1 to the Serial 1 terminals of the previous device
and the next device.
2. Connect Serial 2 to the Serial 2 terminals of the previous device
and the next device.
3. Connect Shield In to Shield Out of the preceding device. Connect
Shield Out to Shield In of the next device. If the NIU is the first
device on a bus, Shield In can be left unconnected. If it is the last
device on a bus, Shield Out can be left unconnected.
4. When inserting two wires into the same terminal block position, the
wire size must be 0.86mm2
(18AWG) or smaller. Both wires should
be of the same size and style. Do not mix stranded with solid wire
in the same position.If either bus will terminate at the NIU, connect a 75, 100, 120, or 150-
ohm terminating resistor across the Serial 1 and Serial 2 terminals. The
use of a ferrule is recommended to crimp each resistor lead to the
corresponding serial line. If ferrules are not used, twist each resistor lead
with the corresponding serial line and solder them together before
inserting the wires into the terminal block.
System Bus Installation Guidelines
The serial bus can be treated as a Class 2 circuit when appropriate
wiring practices are followed. Maximum bus lengths may be affected
when installation requires the high-voltage rated CM rating. CM types
can replace CL2, but not vice versa.
Do not mix cables of different impedance, regardless of cable run length.
Do not mix cable types in long and/or noisy installations. Other, smallsize twisted pair shielded wire of unspecified impedance can be used for
