1771-OJA 脈沖輸出擴(kuò)展模塊

描述:Allen-Bradley 1771-OJ輸出模塊是Allen-Bradley/羅克韋爾自動(dòng)化PLC 5系列的脈沖輸出擴(kuò)展模塊。它配備了一個(gè)現(xiàn)場(chǎng)接線臂稱為艾倫-布拉德利1771-WB現(xiàn)場(chǎng)接線臂。1771-OJ脈沖輸出擴(kuò)展模塊可與步進(jìn)控制器模塊和現(xiàn)場(chǎng)接線臂一起使用，以創(chuàng)建完整的步進(jìn)電機(jī)定位組件。相同的步進(jìn)控制器模塊可以控制多達(dá)3個(gè)脈沖輸出擴(kuò)展模塊，如1771-OJ模塊。1771-OJ脈沖輸出擴(kuò)展模塊設(shè)計(jì)用于1軸機(jī)床應(yīng)用。

Allen-Bradley的1771-OJ PLC 5脈沖輸出擴(kuò)展模塊是步進(jìn)電機(jī)定位組件的一個(gè)組件，它提供可編程控制器的步進(jìn)電機(jī)的可編程控制，并提供每個(gè)I/O機(jī)箱從1軸到3軸的模塊化擴(kuò)展。擴(kuò)展模塊在5V直流背板電流下消耗800mA，它使用輔助電源，額定功率為+5-30V DC，在340mA(最大)下，峰值紋波小于步進(jìn)轉(zhuǎn)換器的規(guī)定值。1771-OJ支持2種輸入模式(JUG和STOP)，在JUG模式下，從1軸到3軸的輸入信號(hào)延遲時(shí)間為35-120ms，在STOP模式下，信號(hào)延遲為250ms。

1771-OJ具有1.0V(高)和0.8V DC(低狀態(tài))的電壓范圍，并具有內(nèi)部1.6千歐姆的拉電阻，該模塊與開路集電極邏輯器件兼容。在5V DC時(shí)最大導(dǎo)通電流為2.3mA，在30V DC時(shí)最大導(dǎo)通電流為18.6mA，輸出電壓范圍為-2.6V DC(高)，+0.7V DC(低)，輸出電流為100mA，模塊最大輸出電流為100mA。1771-OJ在100mA最大電流下的最壞情況下上升/下降時(shí)間為0.6ms，脈沖占空比為50%。該模塊使用40英尺的Belden 8771絞合銅線，每個(gè)終端只有一根線，通過在引腳8和10以及引腳22和24之間插入連接器帶，將其鍵接到I/O背板上。1771-OJ的工作溫度范圍為0- 60c，無冷凝濕度為5-95%，模塊通過CE, CSA, UL和C-TICK認(rèn)證。

Description: The Allen-Bradley 1771-OJ output module is a pulse output expander module from the Allen-Bradley/Rockwell Automation PLC 5 series. It comes with a field wiring arm known as the Allen-Bradley 1771-WB field wiring arm. The 1771-OJ pulse output expander module can be used along with a stepper controller module and a field wiring arm to create a complete stepper motor positioning assembly. Up to 3 pulse output expander modules like the 1771-OJ module can be controlled by the same stepper controller module. The 1771-OJ pulse output expander module is designed to be used in 1-axis machine applications.

The 1771-OJ PLC 5 Pulse Output Expander Module by Allen-Bradley is a component of the Stepper Motor Positioning Assembly which provides programmable control of the stepper motor of the programmable controller and provides modular expansion of axes from 1 to 3 axis per I/O chassis. The expander module draws 800mA at 5V DC backplane current and it uses an auxiliary power supply with a power rating of +5-30V DC at 340mA (max) with a peak-to-peak ripple less than the specified value for the stepper translator. The 1771-OJ supports 2 input modes (JUG and STOP) with an input signal delay time of 35-120ms from 1 axis through 3 axes in the JUG mode and the signal is a delay for 250ms in the STOP mode.

The 1771-OJ has a voltage range of 1.0V (High) and 0.8V DC (Low state) and with an internal 1.6 Kilo Ohms pull-resistor, the module is compatible with Open Collector Logic Devices. It has a maximum ON-state current of 2.3mA per input at 5V DC and 18.6mA at 30V DC and an output voltage range of -2.6V DC (High), and +0.7V DC (low) at 100mA output current, and the maximum output current of the module is 100mA. The 1771-OJ has 0.6ms worst case rise/fall time at 100mA maximum current and it has a 50% pulse duty cycle. The module uses a 40ft Belden 8771 stranded copper wire with a single wire per terminal and it is keyed to the I/O backplane by inserting connector bands between pins 8 and 10 and pins 22 and 24. The 1771-OJ’s operating temperature range is 0-60 0C at 5-95% non-condensing humidity and the module is CE, CSA, UL, and C-TICK certified.
