3ASC25H209通讯模块,3ASC25H209如何使用
辅助接线板的端子分配
所有端子内部连接在一起的辅助接线板可用于3ASC25H209
I/O模块的额外接线端子。它们也可用于额外接地、回路或公用连接。
带箱式端子（目录号IC670TBM002）的辅助接线板有13个
端子，每个端子可容纳一个AWG#14（平均2.1mm2横截面）到AWG#22
（平均横截面积0.36mm2）导线，或两条AWG#18以下的导线（平均横截面积0.86mm2）。这个
带隔离栅端子的辅助接线板（目录号IC670TBM001）有九个
端子，3ASC25H209通讯模块每个端子可容纳一条或两根AWG#14（平均交叉2.1mm2）以下的电线
Terminal Assignments for Auxiliary Terminal Blocks
Auxiliary Terminal Blocks which have all terminals internally connected together can be used for
extra wiring terminals for I/O modules. They can also be used for extra ground, return, or common
connections.
The Auxiliary Terminal Block with box terminals (catalog number IC670TBM002) has 13
terminals, each of which accommodates one AWG #14 (avg 2.1mm2 cross section) to AWG #22
(avg 0.36mm2 cross section) wire, or two wires up to AWG #18 (avg. 0.86mm2 cross section). The
Auxiliary Terminal Block with barrier terminals (catalog number IC670TBM001) has nine
terminals, each of which can accommodate one or two wires up to AWG #14 (avg 2.1mm2 cross
section)
