Analog Voltage Output
When voltage short circuit is detected, the module will generate an alarm and stop
output. An error code can be used to find out which channel is reporting error. (No
alarm will be generated when output is 0V)
Analog Voltage Output
When current open circuit is detected, the module will generate an alarm and stop
output. An error code can be used to find out which channel is reporting error. (No
alarm will be generated when output is 0mA)
Disconnection Detection
A channel alarm will be generated when input exceeds allowable range. In 1-5V /
4-20mA mode, disconnection can be detected when voltage is 0v or current is 0mA.
Analog Input – Fast Conversion Mode
6.5
The conversion time per channel is 2ms. The total required conversion time is
calculated by multiplying 2ms by the number of channels, for example, 4 channels
will take 8ms for conversion. In fast conversion mode, where only one channel is
used, the conversion time can be reduced to 500us.
Fast Conversion Mode can be enabled by setting the corresponding register to 0.5ms.
Under this mode, only one channel can be used. If channel 0 is not closed, the rest of
the channels will not be able to perform conversion. If channel 0 is closed where
