    • An analog input device including a scanning circuit including a first insulation transformer insulating an analog signal inputted from a thermocouple, a power supply section charging a test voltage used for disconnection detection of the thermocouple, a second insulation transformer in which the scanning circuit and the power supply section are connected in parallel, and a control circuit for outputting a pulse signal to be inputted to the second insulation transformer. The second insulation transformer insulates and transfers a drive pulse for switching the scanning circuit and a power supply pulse for feeding power to the power supply section. The control circuit carries out a timing control so that the drive pulse and the power supply pulse are not outputted at the same time. Accordingly, an insulation transformer for application of a test voltage is not required, and thus the total number of the components is reduced to a great extent and reductions in costs and size thereof are realized.
    • 一种模拟输入装置,包括:扫描电路,包括绝缘从热电偶输入的模拟信号的第一绝缘变压器;对用于热电偶的断开检测的测试电压进行充电的电源部;第二绝缘变压器,其中扫描电路和电源 供电部分并联连接的控制电路和用于输出要输入到第二绝缘变压器的脉冲信号的控制电路。 第二绝缘变压器绝缘并传送用于切换扫描电路的驱动脉冲和用于向电源部分供电的电源脉冲。 控制电路执行定时控制,使得驱动脉冲和电源脉冲不被同时输出。 因此,不需要用于施加测试电压的绝缘变压器,从而在很大程度上降低了组件的总数,并且实现了成本和尺寸的降低。

    • An analog input device according to the present invention includes a scanning circuit (3) including a first insulation transformer (T1) for insulating an analog signal inputted from a thermocouple (10), a power supply section (2) for charging a test voltage used for disconnection detection of the thermocouple (10), a second insulation transformer (T2) in which the scanning circuit (3) and the power supply section (2) are connected in parallel, and a control circuit (8) for outputting a pulse signal to be inputted to the second insulation transformer (T2). In the analog input device, the second insulation transformer (T2) insulates and transfers a drive pulse (41) for switching the scanning circuit (3) and a power supply pulse (42) for feeding power to the power supply section (2). The control circuit (8) carries out a timing control so that the drive pulse (41) and the power supply pulse (42) are not outputted at the same time. Accordingly, an insulation transformer for application of a test voltage is not required, and thus the total number of the components is reduced to a great extent and reductions in costs and size thereof are realized.
    • 根据本发明的模拟输入装置包括:扫描电路(3),包括用于绝缘从热电偶(10)输入的模拟信号的第一绝缘变压器(T1);用于对所使用的测试电压进行充电的电源部分(2) 对于热电偶(10)的断开检测,并联连接有扫描电路(3)和电源部(2)的第二绝缘变压器(T2)和用于输出脉冲信号的控制电路(8) 被输入到第二绝缘变压器(T2)。 在模拟输入装置中,第二绝缘变压器(T2)绝缘并传送用于切换扫描电路(3)的驱动脉冲(41)和用于向电源部分(2)供电的电源脉冲(42)。 控制电路(8)执行定时控制,使得驱动脉冲(41)和电源脉冲(42)不被同时输出。 因此,不需要用于施加测试电压的绝缘变压器,从而在很大程度上降低了组件的总数,并且实现了成本和尺寸的降低。
