BENTLY 2300/25-00開關(guān)量輸出模塊

BENTLY 2300/25-00開關(guān)量輸出模塊邏輯地也叫機器邏輯地、主機電源地，是計算機內(nèi)部的邏輯電平負端公共地，也是+5V等的電源輸出地。如CPU的正負5伏、正負12伏的負端。需要接入公共接地極。
2.3屏蔽地（AG，Analog Grounding）
也叫模擬地，它可以把現(xiàn)場信號傳輸時所受到的干擾屏蔽掉，以提高信號精度。DCS系統(tǒng)中信號電纜的屏蔽層應做屏蔽接地。線纜屏蔽層必須一端接地，防止形成閉合回路干擾。鎧裝電纜的金屬鎧不應作為屏蔽保護接地，必須是銅絲網(wǎng)或鍍鋁屏蔽層接地。接入公共接地極。
2.4本安地
應獨立設置接地系統(tǒng)，接地電阻≤4Ω。本安地的接地系統(tǒng)應保持獨立，與廠區(qū)電氣地網(wǎng)或其它儀表系統(tǒng)接地網(wǎng)的距離應在5m以上。
三、DCS系統(tǒng)接地方式
1、S7-1200 CPU 從固件版本V4.1起開始支持組態(tài)控制功能，使模塊的組態(tài)和安裝更加靈活。
2、設DCS系統(tǒng)專用獨立的接地網(wǎng)；
3、設DCS專用接地網(wǎng)，經(jīng)接地線、再接至電氣接地網(wǎng)。Logically
Also called machine logic ground and host power ground, it is the common ground of the negative terminal of the logic level inside the computer and also the power output ground of+5V, etc. For example, the negative end of the CPU with positive and negative 5V and positive and negative 12V. It is required to connect to the common grounding electrode.
2.3 Shielding (AG, Analog Grounding)
Also called analog ground, it can shield the interference received during the field signal transmission to improve the signal accuracy. Shielding layer of signal cable in DCS system shall be grounded. One end of the cable shielding layer must be grounded to prevent closed loop interference. The metal armouring of armored cables shall not be used as shielding protection grounding, but must be grounded with copper wire mesh or aluminized shielding layer. Connect to the common grounding electrode.
2.4 Intrinsically safe place
The grounding system shall be set independently, with the grounding resistance ≤ 4 Ω. The grounding system of intrinsically safe grounding shall be independent, and the distance from the electrical grounding grid or other instrument system grounding grid in the plant area shall be more than 5m.
3、 DCS system grounding mode
1. The S7-1200 CPU supports the configuration control function since the firmware version V4.1, which makes the module configuration and installation more flexible.
2. Independent grounding grid dedicated for DCS system shall be set;
3. DCS special grounding grid is set, which is connected to the electrical grounding grid through the grounding wire.
