Abstract
PURPOSE:To improve a switching responsiveness and to eliminate the variance by mounting an input part and an output part into one car and mounting a logical circuit into the internal part. CONSTITUTION:An input part 1 connected to the input circuit of a programmable controller PC 3 and an output part 2 connected to an output circuit are mounted on one card and between the input part 1 and the output part 2, logical circuits 10, 11 and 12 which go to ON under the constant conditions are mounted. Namely, the logical circuit 10 is the circuit to output when all the inputs of relays R4 and R5 are a relay W2 are executed, and the logical circuit 11 is the circuit to output when either of the outputs of the logical circuit 10 or a relay W3 is executed. Further, the logical circuit 12 outputs when both outputs of the logical circuit 11 and a relay W4 are executed. Thus, the time lag due to the point of time to step on limit switches 4 and 5 and the variance can be eliminated.
