Switch output
For HART devices, the switch output is available as an option. See product structure, feature 20:
"Power Supply, Output", option B: "2-wire; 4-20mA HART, switch output"
Devices with PROFIBUS PA and FOUNDATION Fieldbus always have a switch output.
Switch output
Function Open collector switching output
Switching behavior Binary (conductive or non-conductive), switches when the programmable switch
point is reached
Failure mode non-conductive
Electrical connection values U = 16 to 35 V
Internal resistance R
The voltage drop at this internal resistance has to be taken into account on
planning the configuration. For example, the resulting voltage at a connected
relay must be sufficient to switch the relay.
Insulation voltage floating, Insulation voltage 1 350 V
Switch point freely programmable, separately for switch-on and switch-off point
Switching delay freely programmable from 0 to 100 s, separately for switch-on and switch-off
point
Number of switching cycles corresponds to the measuring cycle
Signal source • Level linearized
device variables • Distance
• Terminal voltage
• Electronic temperature
• Relative echo amplitude
• Diagnostic values, Advanced diagnostics
Number of switching cycles unlimited
