Analog Normal Operating Ranges

(1)

(1) The over- or under-range flag will come on when either the High Clamp or the Low Clamp values are exceeded. When either

range flag is set, the module clamps the corresponding channel’s output to the High Clamp or the Low Clamp value. Unless

latched, the flag automatically resets when directed to a value between the High Clamp and the Low Clamp values. The

output channel value always returns to normal operation when directed to a value allowed by the High Clamp and Low

Clamp values (even if latching of the Clamp status bits is enabled).

0…20 mA, 4…20 mA, +/-10V DC, 0…10V DC, 0…5 V DC, 1…5V DC
