该测试台可分别运用于程序自动测试和单项半自动测试,对我段使用的十三种安全型继电器的电气性能都能进行测试。为了使用简便只用了一个测试座板,测试类型通过按钮选择,按钮继电器互相间有联锁,每次只能可靠的吸起一个继电器,从而保证了电路按一定程序动作。 The test bench can be used for automatic test program and a single semi-automatic test, I used in paragraph 13 kinds of safety relays can be tested for electrical performance. For ease of use, only one test seat plate is used. The test type is selected by the button. The button relays are interlocked with each other, so that only one relay can be sucked reliably at a time, thereby ensuring that the circuit operates according to certain procedures.
