NX-series Safety Control Unit User’s Manual (Z930)
Terminal Blocks for Safety I/O Units come in two types depending on the number of terminals that can
be used. There are 8-terminal and 16-terminal Terminal Blocks.
You can use only one of the two types of terminal blocks given above with a Unit that has a screwless
clamping terminal block.
The terminal block must have the same number of terminals that the Unit is designed for.
Additional Information
The 8-terminal block does not have terminal holes and release holes for the following terminals.
• A2, A4, A6, A8, B2, B4, B6, and B8
There are two types of Terminal Blocks in terms of current capacity, 10 A for the NX-TB2 Terminal
Blocks and 4 A for the NX-TB1 Terminal Blocks.
To differentiate between the two types of Terminal Blocks, use the terminal number column indications.
A Terminal Block with white letters on a dark background is an NX-TB2 Terminal Block.
You can mount either type of Terminal Block to a Unit with a terminal current capacity of 4 A max.
If the terminal current capacity is greater than 4 A, you can mount only an NX-TB2 Terminal
Block.
Refer to A-15 Version Information on page A-87 for the models of the Terminal Blocks that you can
mount to each model of Safety I/O Unit.
• Applicable Terminal Blocks for Each Unit Model
The following table gives the Terminal Blocks that are applicable to each Unit.
Precautions for Correct Use
You can mount either an NX-TB1 or NX-TB2 Terminal Block to a Unit with a termi-
nal current capacity of 4 A.
Even if you mount an NX-TB2 Terminal Block, the current specification does not change
because the terminal current capacity of the Unit is 4 A.
Refer to the I/O power supply terminal current capacities given in 2-2 Specifications of Individ-
ual Units on page 2-3 for the terminal current capacity specifications of the Units.
Refer to A-10 Terminal Block Model Numbers on page A-80 for the model numbers of the Ter-
minal Blocks.
(C) Terminal holes The wires are inserted into these holes.
