NU8976A99處理器模塊,NU8976A99配置教程
端子5至46用于現(xiàn)場設(shè)備。每個終端接受一個AWG#14線（平均橫截面2.1mm2），2 AWG#14（2.1mm2交叉截面）實心導(dǎo)線，或兩個AWG#16（每個平均1.3mm2橫截面）絞合線。任何電路都可以是輸入或輸出。連接場的一個端子設(shè)備連接到直流電源，另一個連接到模塊（端子10-41）。所有輸入/輸出設(shè)備必須返回同一電源電路。根據(jù)布局和電流負(fù)載，正極和負(fù)極連接可以通過總線連接，并通過單線連接到塊或電源。

Terminals 5 to 46 are for field devices. Each terminal accepts one AWG
#14 wire (avg 2.1mm2 cross section), two AWG #14 (2.1mm2
cross
section) solid wires, or two AWG #16 (each avg 1.3mm2
in cross section)
stranded wires.
Any circuit can be an input or output. Connect one terminal of a field
device to DC power and the other to the block (terminals 10-41). All I/O
devices must return to the same power circuit.
Depending on layout and current loads, positive and negative
connections can be bussed and made by single wires to the block or
power source.
Connections for a DC Source Block
For a Source block, connect outputs to the negative side of the power
supply and inputs to the positive sideIf circuit power is not removed at the same time as block power, the
block may power up when multiple inputs are activated, even
though one leg of power has been removed from the block.
If you want to disable the block without removing power from input
devices, use a Block Puller to unplug the Electronics Assembly. Do not
disconnect H or N to remove power.Connections for a DC Sink Block
For a Sink block, connect outputs to the positive side of the power supply
and inputs to the negative side. Connect a DC source to the DC+
terminals (6-9) and the return to the DC- terminals (42-46)DC Sink Block, Power Disconnects
Since block power is the same as circuit power, it is important to wire
block power disconnects so that block power and input power will be
removed at the same time. Locate the power disconnect as shown
below. DC SINK

CAUTION
If circuit power is not removed at the same time as block power,
the block may power up when multiple inputs are activated, even
though one leg of power has been removed from the block.
If you want to disable the block without removing power from input
devices, use a Block Puller to unplug the Electronics Assembly. Do not
disconnect H or N to remove power.
