HONEYWELL 51199929-100开关量输入模块
PLC和转换器之间的接口有两种可能，控制板SDCS-CON-1。第一种可能包括：SDCS-IOB-1板，可安装在转换器模块内。另一个由SDCS-IOB2x和SDCS-IOB-3板组成。如果这些如果使用两块板，则必须将其安装在转换器外部。除此之外，SDCSIOE-1还可以扩展I/O。带控制板的转换器SDCS-CON-2可以以4种不同的方式连接到控件
该装置通过模拟/数字链路。四个中只有一个可以同时使用选项（说明输入/输出见第SDCS-CON-2章）。此外为此，SDCS-IOE-1可以扩展I/O。SDCS-IOB-1板可安装在配备控制板的转换器模块SDCS-CON-1。
SDCS-IOB-1板具有8个数字输入、7个数字输出、5个模拟输入，包括转速发生器接口、2个模拟输出、一个实际电流和增量编码器接口的专用模拟输出。如本章开头所述，有配置输入/输出的各种选项。
板IOB-2x具有8个数字输入和8个数字输出。
存在三种不同的类型，它们在输入电压电平：
SDCS-IOB-21 24…48V直流
SDCS-IOB-22 115伏交流电
SDCS-IOB-23 230伏交流电
输入通过以下方式进行滤波和电流隔离：
使用光耦合器。输入可以形成两个电流使用X7:1或X7:2进行分组。
如果使用这些板，则必须安装它们在DCS模块外部。它们必须安装在这样，导电支架与装置的接地连接良好。输入电阻：见图表。输入平滑时间常数：参见图表。
可以改变通道7和8的平滑时间常数；参见板
将读取的输入通道的功能可通过以下方式定义软件默认值显示在软件图中数字输入电源：48V/50mA；不是galv。与DCS隔离电子学
如果输入由内部+48 V（X7:3和/或X7:4）连接提供必须从DCS 500模块的X7:1和/或X7:2接地。在里面默认条件接地与转换器的机架相同。
如果输入由任何外部电源提供（+48 V直流、115 V交流或230 VAC）中性线/线必须连接到X7:1或X7:2。如果输入应使用相同的电压电平进行控制，但使用两个不同的电压
可能具有两个不同接地电平的电源，第一条中性线应连接到X7:1，第二个连接到X4:2。在这种情况下，将输入连接到X8:2的跳线Wx必须被切断。
对于其他跳线Wx也需要相同的方法。
高频接地由100 nF电容器完成
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
