HONEYWELL 51199929-100開關(guān)量輸入模塊
PLC和轉(zhuǎn)換器之間的接口有兩種可能，控制板SDCS-CON-1。第一種可能包括：SDCS-IOB-1板，可安裝在轉(zhuǎn)換器模塊內(nèi)。另一個由SDCS-IOB2x和SDCS-IOB-3板組成。如果這些如果使用兩塊板，則必須將其安裝在轉(zhuǎn)換器外部。除此之外，SDCSIOE-1還可以擴(kuò)展I/O。帶控制板的轉(zhuǎn)換器SDCS-CON-2可以以4種不同的方式連接到控件
該裝置通過模擬/數(shù)字鏈路。四個中只有一個可以同時使用選項（說明輸入/輸出見第SDCS-CON-2章）。此外為此，SDCS-IOE-1可以擴(kuò)展I/O。SDCS-IOB-1板可安裝在配備控制板的轉(zhuǎn)換器模塊SDCS-CON-1。
SDCS-IOB-1板具有8個數(shù)字輸入、7個數(shù)字輸出、5個模擬輸入，包括轉(zhuǎn)速發(fā)生器接口、2個模擬輸出、一個實(shí)際電流和增量編碼器接口的專用模擬輸出。如本章開頭所述，有配置輸入/輸出的各種選項。
板IOB-2x具有8個數(shù)字輸入和8個數(shù)字輸出。
存在三種不同的類型，它們在輸入電壓電平：
SDCS-IOB-21 24…48V直流
SDCS-IOB-22 115伏交流電
SDCS-IOB-23 230伏交流電
輸入通過以下方式進(jìn)行濾波和電流隔離：
使用光耦合器。輸入可以形成兩個電流使用X7:1或X7:2進(jìn)行分組。
如果使用這些板，則必須安裝它們在DCS模塊外部。它們必須安裝在這樣，導(dǎo)電支架與裝置的接地連接良好。輸入電阻：見圖表。輸入平滑時間常數(shù)：參見圖表。
可以改變通道7和8的平滑時間常數(shù)；參見板
將讀取的輸入通道的功能可通過以下方式定義軟件默認(rèn)值顯示在軟件圖中數(shù)字輸入電源：48V/50mA；不是galv。與DCS隔離電子學(xué)
如果輸入由內(nèi)部+48 V（X7:3和/或X7:4）連接提供必須從DCS 500模塊的X7:1和/或X7:2接地。在里面默認(rèn)條件接地與轉(zhuǎn)換器的機(jī)架相同。
如果輸入由任何外部電源提供（+48 V直流、115 V交流或230 VAC）中性線/線必須連接到X7:1或X7:2。如果輸入應(yīng)使用相同的電壓電平進(jìn)行控制，但使用兩個不同的電壓
可能具有兩個不同接地電平的電源，第一條中性線應(yīng)連接到X7:1，第二個連接到X4:2。在這種情況下，將輸入連接到X8:2的跳線Wx必須被切斷。
對于其他跳線Wx也需要相同的方法。
高頻接地由100 nF電容器完成
There are two possibilities available for the interface between a PLC and the converter with a control board SDCS-CON-1. The first one consists of
the SDCS-IOB-1 board, which can be mounted inside the converter module. The other one consists of the SDCS-IOB2x and SDCS-IOB-3 board. If these
two boards are in use they must be mounted outside the converter.
In addition to this an extension of I/O′s by SDCSIOE-1 is possible.The converter with a control board SDCS-CON-2
can be connected in 4 different ways to a control
unit via analogue/digital links. Only one of the four
choices can be used at the same time (Description
of the I/O's see chapter SDCS-CON-2). In addition
to this an extension of I/O′s by SDCS-IOE-1 is possible.The SDCS-IOB-1 board can be mounted inside the
converter module equipped with a control board
SDCS-CON-1.
The SDCS-IOB-1 board has 8 digital inputs, 7 digital outputs, 5 analogue inputs including a tacho generator interface, 2 analogue outputs, one dedicated analogue output of actual current and incremental encoder interface.As described at the beginning of the chapter, there are
various options for configuring the inputs/outputs.
The board IOB-2x has 8 digital inputs and 8 digital
outputs.
There are three different types existing, which differ at
the input voltage level:
SDCS-IOB-21 24...48V DC
SDCS-IOB-22 115 V AC
SDCS-IOB-23 230 V AC
The inputs are filtered and galvanically isolated by
using opto couplers. Inputs can form two galvanically
separated groups by using either X7:1 or X7:2.
If these boards are in use, they have to be mounted
outside the DCS module. They must be mounted in a
way, that the conductive supports have a good connection to ground of the installation.
Input resistance: see diagram.
Input smoothing time constant: see diagram.
Smoothing time constant of channel 7 and 8 can be changed; see layout of the
board.
The functionality of the input channels, which will be read, can be defined by
software; default values are shown within the software diagrams
Power supply for digital inputs: 48V / 50mA; not galv. isolated from the DCS
electronics!
If the inputs are supplied from the internal +48 V (X7:3 and/or X7:4) a connection
must be done from either X7:1 and/or X7:2 to ground of the DCS 500 modules. In
default condition ground is identical to the converter's frame.
If the inputs are supplied by any external source (+48 V DC, 115 V AC or 230 V
AC) the neutral line / - line must be connected to either X7:1 or X7:2. If the inputs
should be controlled with the same voltage level, but from two different voltage
sources, having probably two different ground levels, the first neutral line should
be connected to X7:1 and the second to X7:2. In this case the jumpers Wx connecting the inputs to X7:2, but controlled by the source, connected to X7:1, must
be cut off.
The same method is needed for the other jumpers Wx.
High frequency grounding is done by 100 nF capacitor
