IS200EPSMG1ABB燃機(jī)模塊,IS200EPSMG1ABB使用方法
如果CPU進(jìn)入停止模式或重置，模塊的狀態(tài)可以默認(rèn)為0/4mA或保持最后狀態(tài)。通過配置DEF0/4跳線來選擇所需狀態(tài)在模塊上的可拆卸端子板連接器上。如果未安裝跨接導(dǎo)線，則如果連接了備用用戶電源，輸出將在停止或重置時(shí)保持最后狀態(tài)當(dāng)系統(tǒng)電源下降時(shí)。如果存在DEF0/4跳線，則模塊默認(rèn)為4 mA停止或重置時(shí)，在4至20 mA范圍內(nèi)或在0至20 mA范圍內(nèi)為0 mA。每個(gè)跳線一個(gè)模塊用于對(duì)保持最后狀態(tài)或DEF0/4的兩個(gè)輸出進(jìn)行編程。
IS200EPSMG1ABB燃機(jī)模塊每個(gè)模塊輸出可用作電流源或精度較低的電壓源。A.電壓在對(duì)應(yīng)于電流輸出的VOUTx處輸出。選擇電流或電壓輸出通過輸入/輸出端子板上的跨接線實(shí)現(xiàn)。如果未安裝跳線，則模塊用作電流源。如果存在JMPVx跳線，則模塊將作為電壓源。每個(gè)通道都可以選擇電壓或電流。設(shè)置電流輸出范圍決定電壓范圍。電壓范圍可以通過使用250歐姆電阻器代替JMPVx到IOUTx的電壓跳線。下表顯示范圍設(shè)置和電壓輸出之間的關(guān)系。模塊的主要電源是由PLC提供的隔離+24 VDC電源電源。模塊的輸入/輸出端子板上還為用戶提供了兩個(gè)端子供電+24伏。這允許您提供備用電源，以便輸出可以如果內(nèi)部電源丟失并且選擇了保持最后狀態(tài)，則繼續(xù)保持其值。你可以還需要提供模塊電壓，以減少PLC隔離+24 VDC電源上的負(fù)載供給當(dāng)施加的電壓高于隔離的+24 VDC時(shí)，將使用用戶電源電源電壓范圍為21.5伏至26.5伏。模塊中產(chǎn)生約+24V的內(nèi)部電壓源，以驅(qū)動(dòng)電流回路輸出。模塊上的電流環(huán)路驅(qū)動(dòng)器是源類型驅(qū)動(dòng)器。這意味著電流從電流回路輸出中流出，以便用戶的負(fù)載可以返回到公共。A.電阻器和公共回路串聯(lián)，以限制接地回路電流。
The state of the module if the CPU goes to the STOP mode or RESET, can be either Default to 0/4
mA or Hold-Last-State. Selection of the desired state is made by configuring the DEF0/4 jumper
on the detachable terminal board connector on the module. If the jumper is not installed, the
outputs will Hold-Last-State on STOP or RESET provided that a backup user supply is connected
when the system power goes down. If the DEF0/4 jumper is present, the module defaults to 4 mA
on the 4 to 20 mA range or 0 mA on the 0 to 20 mA range on STOP or RESET. One jumper per
module is used to program both outputs for Hold-Last-State or DEF0/4.
Each module output may be used as a current source or as a less accurate voltage source. A
voltage is output at VOUTx that corresponds to the current output. The selection of current or
voltage output is made with a jumper on the I/O terminal board. If no jumper is installed, the
module performs as a current source. If the JMPVx jumper is present, the module performs as a
voltage source. Each channel has the option of selecting voltage or current. The setting of the
current output range determines the voltage range. The voltage range can be increased by using a
250 ohm resistor in place of the voltage jumper from JMPVx to IOUTx. The following table shows
the relationship between range settings and voltage outputs.The primary power source for the module is the isolated +24 VDC power supplied by the PLC
power supply. Two terminals are also provided on the module’s I/O terminal board for user
supplied +24 volts. This allows you to provide a standby power supply so that the outputs can
continue to hold their value if the internal supply is lost and Hold-Last-State is selected. You may
also want to supply the module voltage to reduce the load on the PLC isolated +24 VDC power
