IS220PTURH1B通用燃機(jī)卡件,IS220PTURH1B英文說明
總線安裝指南非屏蔽導(dǎo)線的最大外露長(zhǎng)度應(yīng)為5cm（2in）。
為了增加保護(hù)，每個(gè)屏蔽排流線應(yīng)使用意大利面管，防止屏蔽進(jìn)出電線相互接觸，或接觸信號(hào)線。1.將串行1連接到先前設(shè)備的串行1端子和下一個(gè)設(shè)備。
2.將串行2連接到先前設(shè)備的串行2端子和下一個(gè)設(shè)備。
3.將屏蔽連接到前面設(shè)備的屏蔽。連接屏蔽出到屏蔽下一個(gè)設(shè)備。如果牛是第一個(gè)總線上的設(shè)備，屏蔽可以保持未連接。如果是最后一次總線上的設(shè)備，屏蔽可以保持未連接。
IS220PTURH1B通用燃機(jī)卡件4、將兩根導(dǎo)線插入同一接線板位置時(shí)導(dǎo)線尺寸必須為0.86mm2（18AWG）或更小。兩條電線應(yīng)大小和樣式相同。不要將絞合線與實(shí)心線混合在相同的位置。如果任一總線終止于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)電阻器引線壓接至對(duì)應(yīng)的串行線。如果未使用套圈，則扭轉(zhuǎn)每個(gè)電阻器導(dǎo)線與相應(yīng)的串行線焊接在一起之前將導(dǎo)線插入接線板。系統(tǒng)總線安裝指南適當(dāng)時(shí)，串行總線可被視為2級(jí)電路遵循接線實(shí)踐。最大總線長(zhǎng)度可能會(huì)受到影響當(dāng)安裝需要高壓額定CM額定值時(shí)。CM類型可以替換CL2，但不能反之亦然。無論電纜敷設(shè)長(zhǎng)度如何，都不要混合使用不同阻抗的電纜。請(qǐng)勿在長(zhǎng)距離和/或嘈雜的安裝中混合電纜類型。其他未指定阻抗的小尺寸雙絞線屏蔽線可用于使用75歐姆終端，短距離運(yùn)行50英尺或更少。選擇電線類型可能受到地方和國(guó)家規(guī)范及行業(yè)的限制標(biāo)準(zhǔn)。咨詢電纜制造商以確定電纜的適用于特定類型的安裝。
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
