7DO138 是一款数字输出模块 8个输出24 VDC
品牌：B&R。
型号：7DO138.70。
数字输出：8个输出24 VDC，0.5 A，防短路，热过载保护。
旋入模块：模块输入端如果设置为“常开检线”状态输入，模块输入线末端（远离模块端）并联一个4.7kΩ的终端电阻；模块输入端如果设置为“常闭检线”状态输入，模块输入线末端（远离模块端）串联一个4.7kΩ的终端电阻。模块为有源输出时，有源输出端应并联一个4.7kΩ的终端电阻，并串联一个IN4007二极管。
B&R 7DO138.70的特点如下：
防短路：可以防短路。
热过载保护：有过载自动保护功能。
旋入式接口：采用旋入式接口，方便接线。
7DO138 是一款数字输出模块 8个输出24 VDC
Brand: B&R.
Model: 7DO138.70.
Digital output: 8 outputs 24 VDC, 0.5 A, anti-short circuit, thermal overload protection.
Screw in the module: If the input end of the module is set to "normally open check line" state input, the end of the module input line (away from the module end) is connected with a 4.7kΩ terminal resistor; If the module input is set to "Normally closed line detection", a 4.7kΩ terminal resistor is connected in series at the end of the module input line (away from the module end). When the module has an active output, the active output should be connected by a 4.7kΩ terminal resistor and an IN4007 diode in series.
B&R 7DO138.70 features the following:
Anti-short circuit: can prevent short circuit.
Thermal overload protection: automatic overload protection function.
Screw in interface: Screw in interface, easy to connect.
