Abstract
PURPOSE: To automate the diagnosis of an analog input device and provide this diagnosis device with a function of burn-out, by utilizing a holding circuit of analog input signals for diagnosis purpose.
CONSTITUTION: Signals from an analog input signal source 1 are supplied to a signal holding circuit 2 equipped with a filter function, the output is given to an input circuit 3 through a sampling switch SW1 switched ON-OFF by signals from a control circuit 5 and output corresponding to input is sent out. In this case, a condenser C1 in the circuit 2 receives DC currents from a reference voltage source 4 through a switch SW2 for change and is charged. In a diagnosis mode, the condenser is charged until the quantity of the charge of the condenser C1 reaches fixed value, charge is stopped, a discharge condition of the C1 is read by the output of the circuit 3 and the existence of the trouble of an input device is discriminated in response to the change.
