transducer.
Switch it to Downside stands for the 1
st
analog input should connect to 0~20mA or
4~20mA current output transducer.
Tips:
The wrong side will cause device can't read the analog value.
1/V/mA~3/V/mA
The 2
nd
to 4
th
channel of analog input type switch. If not use this channel then no matter
is upside or downside.
Switch it to upside stands for the related analog input should connect to 0~5V voltage
output transducer.
Switch it to Downside stands for the related analog input should connect to 0~20mA or
4~20mA current output transducer.
