When the state of the logic "H" output from the disconnection detecting comparator 80 continues for a specified time or longer, the filter circuit 84 outputs a signal, showing the presence of abnormality which is the signal of the logic "H".

SOLUTION: This input module 20 for the input circuit is provided with a sensor state detecting circuit 22 arranged in an energizing route from a DC power source 5 to a sensor 4a and capable of inputting a signal expressing the ON of the sensor 4a to a CPU when voltage between input terminals 20a, 20b is more than threshold voltage corresponding to power voltage and a connection state detecting circuit 24 for inputting a signal expressing the normality of wiring with the sensor to the CPU when the inter-terminal voltage is more than a threshold corresponding to a leak current ILeak allowed to flow through a main circuit in the sensor 4a and constituted so that the CPU detects the disconnection of the energizing route when both outputs from the circuits 22, 24 are low levels. When the circuit 22 judges the ON of the sensor 4a, connection between the circuit 24 and the input terminal 20a is interrupted to suppress a current flowing onto the module 20. Consequently the power consumtion of the module 21 can be saved and heat generation can be reduced.
