Analog and Digital Communications

Two active 4-20 mA outputs and a Modbus RS485 digital interface (see Appendix B for
details) are provided with the Condumax II. The 4-20 mA outputs can be set individually
to represent one of the following:
• Hydrocarbon dew point (or signal in mV if in condensate mode)
• Hydrocarbon dew-point analysis pressure
• Water dew-point analysis pressure
• Water dew-point temperature (or moisture content)
NOTE: The maximum output resistance for the 4-20 mA outputs is 500 Ω.
Refer to Section 3.10.4 for the setting of the 4-20 mA outputs via the user interface and
refer to Appendix B.4 on setting the outputs via the Modbus interface.
