HONEYWELL CC-PCF901隔離模塊,CC-PCF901英文說明
輸入/輸出端子板端子分配
下圖顯示了不同類型的輸入/輸出端子塊的端子分配
可與模塊一起使用。帶箱式端子的接線板每個端子有25個端子
單元每個可容納一個AWG#14（平均2.1mm2
橫截面）至AWG#22（平均值CC-PCF901
0.36mm2
橫截面）導線，或AWG#18（平均0.86mm2）以下的兩根導線
橫截面）。當
使用外部跳線，單線容量從AWG#14（2.10mm2）減少
)至AWG#16

I/O Terminal Block Terminal Assignments
The diagrams below show terminal assignments for the different types of I/O Terminal Block that
can be used with the module. The Terminal Block with Box Terminals has 25 terminals for each
module. Each 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). When an
external jumper is used, single-wire capacity is reduced from AWG #14 (2.10mm2
) to AWG #16
(1.32mm2
).
The I/O Terminal Block with Barrier Terminals has 18 terminals per module. Each terminal can
accommodate one or two wires up to AWG #14 (avg 2.1mm2
cross section).
The I/O Terminal Block with Connectors has one 20-pin male connector per modulePower Sources
No loop power is required for this module. The excitation current for the RTDs is provided by the
module, which automatically matches the excitation current to each configured RTD type.
LED
A single indicator shows module status:
? ON: normal operation
? Intermittent flashing: module fault
? OFF: loss of backplane power or fatal fault
