AD Conversion and Preloaded Trigger

4.1.1

ADC

The PCI-8136 provides 6 differential ADC channels. Each channel
consists of two inputs. One for a (+) signal and the other for a (-)
signal. The input signal may have a voltage range from –10 ~
+10V or current range from –20mA ~ 20mA. The following figure
show the A (voltage or current) to D (value read) converting table.
The zero voltage or current is at value 2000.

Related functions:

_8136_A_Initial

(): please refer to section 5.5

_8136_A_Read_Value

(),

_8136_A_Read_Volt

(): please refer

to section 5.5

4.1.2

Voltage Compare

The voltage compare function allows users to set a compare value
by software function. When one ADC signal reaches the pre-set
value, an interrupt will be generated for corresponding channel.

Relative functions:

_8136_A_Set_Compare_Value

(),

_8136_A_Set_Compare_Volt

(),

_8136_S_Set_Int_Factor
