摘要： PROBLEM TO BE SOLVED: To provide an analog input terminal by which the need for the user to correct a program is eliminated by correcting an error of a voltage (current) and outputting a digital value even when receiving an analog signal with the voltage (current) with the error from an analog output device. SOLUTION: An analog input circuit section 10a capable of receiving signals of 4 channels outputs an analog signal (x) received from an analog output device to an A/D converter section 10b. When receiving the analog signal (x) from the analog input circuit section 10a, the A/D converter section 10b converts the analog signal (x) into a digital value that is called a raw count A and outputs it to a CPU section 10c. The CPU section 10c outputs a digital signal X obtained by normalizing the raw count A received from the A/D converter section 10b into a range of 0-6000 to a master station based on a calibration value α and an adjustment value β that are stored in an EEFROM 140 and mentioned later.

摘要： PURPOSE:To detect a disconnection immediately after electricity is supplied from a high potential power source by quickly charging a noise absorbing capacitor through a switching device in the ON state when the high potential power source is turned ON. CONSTITUTION:An analog switch SW as a switching device has one end connected to a high potential power source Vcc2 and the other end connected to a noise absorbing capacitor C1. When the power sources Vcc1, Vcc2 are turned On while the capacitor C1 is not charged, the capacitor C1 is quickly charged through the switch SW in the ON state. When the quick charging is finished, the capacitor C1 comes not to be charged through the switch SW which is turned into the OFF state. Therefore, when a temperature detecting output is fed from a temperature sensor SS with the power sources Vcc1, Vcc2 turned ON, electric noises included in the output are absorbed by the capacitor C1. Accordingly, it is possible to detect a disconnection without being influenced by the electric noises.
