<P>PROBLEM TO BE SOLVED: To obtain a unit type programmable controller in which a cover of a main body is suppressed from being deformed by vibration or impulse while ensuring reduction in size and variation in distance between substrates or twisting of substrates is suppressed. <P>SOLUTION: In a unit type programmable controller, a main body 1 includes a case 2, an input/output substrate 10 fixed within the case 2, a cover 3 provided in the case 2 and a control substrate 5 fixed to the cover 3. Terminal blocks 21 and 22 disposed with the cover 3 interposed therebetween include the first terminal block section 23 fixed to the input/output substrate 10 and the second terminal block section 24 provided while removably overlapping the first terminal block section 23. For the cover 3 and the terminal blocks 21 and 22, projections 4A and 4B of the cover 3 are locked to recesses 27A and 27B of the second terminal block sections 24A and 24B, and the input/output substrate 10 and the control substrate 5 are connected with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
