single channel of optically-isolated current-to-digital conversion. The AD3T
and AD2T modules offer additional channel-to-channel isolation. For the AD3
and AD3T modules, the nominal input range is 4 to 20 mA with an under/over
range capability from less than 3 mA to greater than 35 mA. The AD2T module
has a nominal input range of 0 to 20 mA with an under/over range capability
from less than -1.25 mA to greater than 35 mA. The “T” modules also provide
4,000 V
These modules plug into a Classic Standard analog I/O rack and are secured by
a captive screw.
