2.2.5  AS200 Input/Output Terminals 
  Analog Input 
Two analog signal input channels:   
Item  Voltage Input  Current input 
Analog Signal   
-10 to +10 V 
-20 to 20 mA 
4 to 20mA (for FW V1.08 or later) 
Resolution 
12-bit  11-bit
 
Input impedance 
≧1 MΩ 
250 Ω 
Conversion time 
3 ms / CH 
Analog to digital 
-2000 to 2000 
-1000 to 1000 (-20 to 20 mA) 
Digital value 
SR168 (CH1)  SR169 (CH2) 
You can use the program to read the values in SR to obtain the corresponding A/D conversion value for the 
channel. 
 
  Analog Output 
Two analog signal output channels: 
Item  Voltage output  Current output 
Impedance
