  • Patent number: 8120367
    Abstract: 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.

  • Publication number: 20110254527
    Abstract: In the analog current output circuit according to the present invention, a rising start position and a tilt of an internal control voltage are set such that it crosses, at the maximum of an analog output current, a load end voltage obtained when the resistance of a load is the one near the center of a specification range. According to a comparison result in a comparator, a switch causes a DC/DC converter to input a high reference voltage and causes an output transistor to output a high power supply voltage when the internal control voltage is smaller than the load end voltage and causes the DC/DC converter to input a low reference voltage and causes the output transistor to output a low power supply voltage when the internal control voltage is larger than the load end voltage.
