Switch output
For HART devices, the switch output is available as an option.
• Function:
Open collector switch output
• Switching behavior:
Binary (conductive or non-conductive), switches when the programmable switch-on point/switch-
off point is reached
• Failure mode:
Non-conductive
• Electrical connection data:
U = 16 to 35 V
DC
, I = 0 to 40 mA
• Internal resistor:
R
I
< 880 Ω
The voltage drop at this internal resistor must be taken into account when planning the
configuration. For example, the resulting voltage at a connected relay must be sufficient to switch
the relay.
• Insulation voltages:
Floating, insulation voltage 1 350 V
DC
in relation to power supply and 500 V
AC
ground
• Switch point:
User-programmable, separate for switch-on point and switch-off point
• Switching delay:
User-programmable in the 0 to 100 s range, separate for switch-on point and switch-off point
