Circuit Protections
Channels are wired as inputs and outputs. For channel outputs, this module can
detect an open circuit current loop on each channel in 4 to 20 mA range, current
mode, a short on an output pin in voltage mode, and over temperature conditions
in both current and voltage modes. For input measurement, open wire detection is
available in the form of open circuit inputs going over-range for the voltage and
current ranges.
All 4 input channels are protected at the maximum input voltage of ±24 V in
voltage mode and limit the input current between 30 mA and 60 mA at fault over
current condition in current mode.
Outputs are protected from electrostatic discharge up to 6 kV for indirect and
contact discharge, 8 kV for air discharge. A load resistance greater than 500 Ohm
also triggers this fault.
A short on an output pin in voltage mode is also detected, and output current is
then limited to less than 15 mA. A load less than 1 Kohm resistance also triggers
