Abstract

Abstract A sequence control element comprising a circuit board (231 on which is formed a basic circuit (23b) for sequence control, a relay element (25) that can be detachably connected to the basic circuit, and connectors (23c,23d) that can be connected to the basic circuit and that can also be detachably connected to other sequence control elements, and a sequence controller using said element. The sequence controller is formed by detachably connecting a plurality of sequence control elements which can be attached to or removed from a mounting rail (21) via connectors in single movement. Different sequence control elements can be constituted by simply replacing the circuit board on which a predetermined basic circuit is formed.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 48 words
A sequence control element comprising: a board formed thereon with a basic circuit for a predetermined sequence control; a relay element detachably connectible to the basic circuit of said board; and connectors connected to the basic circuit of said board and detachably connectible to other sequence control elements.
Claim 2
Dependent Claim 48 words
A sequence control element comprising: a board formed thereon with a basic circuit for a predetermined sequence control; a relay element detachably connectible to the basic circuit of said board; and connectors connected to the basic circuit of said board and detachably connectible to other sequence control elements.
Claim 3
Dependent Claim 74 words
A sequence controller using a plurality of sequence control elements each comprising: a board formed thereon with a basic circuit for a predetermined sequence control; a relay element detachably connectible to the basic circuit of said board; and connectors connected to the basic circuit of said board and detachably connectable to other sequence control elements; wherein said plurality of sequence control elements are detachably connected to one another through said connectors on mounting means.
Claim 4
Dependent Claim 74 words
A sequence controller using a plurality of sequence control elements each comprising: a board formed thereon with a basic circuit for a predetermined sequence control; a relay element detachably connectible to the basic circuit of said board; and connectors connected to the basic circuit of said board and detachably connectable to other sequence control elements; wherein said plurality of sequence control elements are detachably connected to one another through said connectors on mounting means.
Claim 5
Dependent Claim 37 words
A sequence controller as set forth in claim 2, characterized in that each of said sequence control elements causes an output in the preceding step to disappear and prepares for delivering an input to the succeeding step.
