信号参考装置外壳电位请注意:
除非另有说明,否则所有信号都引用
0 V电位。在电源组分总成内
(SDCS-POW-1)和所有其他PCB上
通过以下方式与机组外壳牢固连接
在紧固点进行电镀。The digital and analogue inputs can be extended by
means of the SDCS-IOE1 board. This is in addition to
the a.m. solutions.
Fig. 2.5/5: Additional Inputs via SDCS-IOE1
Analogue inputs: extended
Digital inputs: all isolated by means of
optocoupler, the signal status
is indicated by LED
current source for: PT100/PTC element
Description of input signals SDCS-IOE-1
Mechanical system always external, outside the basic unit
Terminals
Screw-type terminals for finely stranded wires up to max. 2.5 mm2
cross-sectional area
Functionality
Ö 7 digital inputs
The functions can be selected by means of the software
The signal status is indicated by an LED
Input voltage: 0...8 V ⇒ "0 signal", 16...31 V ⇒ "1 signal"
Isolated from the unit’s electronics by optocouplers
Potentialwise arranged in two groups (DI 9...DI 12 and DI 13...DI 15)
Time constant of smoothing capacitor: 2 ms
Ö 2 analogue inputs
All as differential inputs; common-mode range ±40 V
Range -10 V/-20 mA...0...+10 V/+20 mA; 4... 20 mA unipolar
RE = 200 kΩ /500 Ω /500 Ω
Resolution: 11 bit + sign
Input 2: range as for input 1,
in addition -1 V/-2 mA...0...+1 V/+2 mA, then common-mode range ±40 V, RE = 20 kΩ
Õ Current source for PT 100 or PTC element evaluation
I
A = 5 mA / 1.5 mA
The signals are referenced to the unit casing potentiaPlease note:
Unless otherwise stated, all signals are referenced to a
0 V potential. Within the power pack subassembly
(SDCS-POW-1) and on all other PCBs, this potential
is firmly connected to the unit’s casing by means of
plating-through at the fastening points.
