Connection
DC-M_Connection 72×72mm type
Contact/Open-collector input
Note) Count 1 terminal [8] is increment, Count 2 terminal [9] is decrement. In case of 90 phase-difference input, when Count 1 is shifted shifted by 90°, it is increment counting, and when Count 2 is shifted 90°, it is decrement counting.
Note) In case of Total counter, [4] [5] [6] terminal are not used.
Note) FG [3] terminals should be grounded.
DC-M_Connection 2×144mm type
Contact/Open-collector input
Note) Terminals [11] and [18] are connected inside
Note) Count 1 [12] is increment counting and Count 2 [13] is decrement counting. In case of 90°phase-difference input, when Count 1 is shifted by 90°, it is increment counting, and when Count 2 is shited by 90°, it is decrement counting.
Note) In case of total counter, [4] [5] [6] [7] [8] [9] [16] [17] terminals are not used.
Note) In case of preset counter (1 preset type), [4] [5] [6] [16] terminals are not used.
Note) FG ([3] terminal) should be grounded.
Caution note)
* Do not use unused terminal as relay terminal.
* Each input to counting, reset and count prohibition is common use for contact and open-collector. Wire to each input and output terminal 2-core shield wire or metal conduit tube as short as possible. Do not lay the wires close to or parallel to line cable, power cable or high voltage line.
* For connection, use M3 pressure connection terminals.
