One example of how to wire to the passive inputs is shown in Figure 3-39.
3.4.2.4. Passive Outputs
Using the Discrete I/O option with passive outputs provides the ability to control high voltage
solenoids or other feeding equipment in the safe area through protective devices such as an
intrinsically safe switch amplifier. The external switch amplifier isolates the lines back to the
IND560x terminal so they remain intrinsically safe while providing switching of a higher AC or DC
voltage. Entity values of the amplifiers must be compared to the IND560x output entity parameters.
Cable capacitance and inductance must also be included.
Devices from two manufacturers that have been tested for correct operation with the IND560x and
can be connected directly to the outputs as shown are:
