1771-OJA 脉冲输出扩展模块

描述:Allen-Bradley 1771-OJ输出模块是Allen-Bradley/罗克韦尔自动化PLC 5系列的脉冲输出扩展模块。它配备了一个现场接线臂称为艾伦-布拉德利1771-WB现场接线臂。1771-OJ脉冲输出扩展模块可与步进控制器模块和现场接线臂一起使用，以创建完整的步进电机定位组件。相同的步进控制器模块可以控制多达3个脉冲输出扩展模块，如1771-OJ模块。1771-OJ脉冲输出扩展模块设计用于1轴机床应用。

Allen-Bradley的1771-OJ PLC 5脉冲输出扩展模块是步进电机定位组件的一个组件，它提供可编程控制器的步进电机的可编程控制，并提供每个I/O机箱从1轴到3轴的模块化扩展。扩展模块在5V直流背板电流下消耗800mA，它使用辅助电源，额定功率为+5-30V DC，在340mA(最大)下，峰值纹波小于步进转换器的规定值。1771-OJ支持2种输入模式(JUG和STOP)，在JUG模式下，从1轴到3轴的输入信号延迟时间为35-120ms，在STOP模式下，信号延迟为250ms。

1771-OJ具有1.0V(高)和0.8V DC(低状态)的电压范围，并具有内部1.6千欧姆的拉电阻，该模块与开路集电极逻辑器件兼容。在5V DC时最大导通电流为2.3mA，在30V DC时最大导通电流为18.6mA，输出电压范围为-2.6V DC(高)，+0.7V DC(低)，输出电流为100mA，模块最大输出电流为100mA。1771-OJ在100mA最大电流下的最坏情况下上升/下降时间为0.6ms，脉冲占空比为50%。该模块使用40英尺的Belden 8771绞合铜线，每个终端只有一根线，通过在引脚8和10以及引脚22和24之间插入连接器带，将其键接到I/O背板上。1771-OJ的工作温度范围为0- 60c，无冷凝湿度为5-95%，模块通过CE, CSA, UL和C-TICK认证。

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.
