Additional Information
• Each Position Interface Unit is compatible with only one of these three types of terminal
blocks. You cannot use a terminal block that does not match the specifications for a particular
Unit.
• The 12-mm-wide terminal block does not have terminal holes and release holes for terminal
numbers A7, A8, B7, and B8.
• The 24-mm-wide terminal block does not have terminal holes and release holes for terminal
numbers A7, A8, B7, B8, C7, C8, D7, and D8.
The following table gives the Terminal Blocks that are applicable to each Unit.
Letter Name Function
(A) Terminal num-
ber indication The terminal number is identified by a column (A through D) and a row (1 through 8).
Therefore, terminal numbers are written as a combination of columns and rows, A1
through A8 and B1 through B8.
For a 24-mm-wide terminal block, the left side contains terminals A1 through A8 and
B1 through B8. The right side contains terminals C1 through C8 and D1 through D8.
The terminal number indication is the same regardless of the number of terminals on
the terminal block, as shown above.
(B) Release hole A flat-blade screwdriver is inserted here to attach and remove the wiring.
(C) Terminal hole The wires are inserted into these holes.
