Emerson VE4003S2B3 Analog Input Cards and Termination Blocks

Meet Ethylene Purification and Certification Demands Using Rosemount CT5800 Continuous Gas Analyzer

• Measure multiple gas components in a single analyzer for reduced total cost of ownership

• Gain faster process insights with measurement update time of <1 second,ensuring reliable process monitoring and control

• High sensitivity and selectivity allow the detection of multiple components and trace

impurities simultaneously while remaining immune to cross-interference effects for greater measurement reliability

• Field-mountable design reduces the need for expensive analyzer shelters and long sample transport line

• Certified flameproof enclosure simplifies installation in hazardous areas

• Patented laser chirp technique analyses the gas continuously down to sub-ppm concentrations, enabling sub-second measurements in real time

System Configurations

The Mini Converter can be used in a point-to-point configuration as described above,

or in a multidrop configuration with the host device configured as the master and one or more programmable controllers configured as slaves.

The multidrop configuration requires a straightthrough (1-to-1) cable from the Mini Converter’s RS-422 port to the first slave PLC’s SNP port.

Other slaves will require a daisy chain connection between slaves.

A maximum of eight devices can be connected in an RS-422 multidrop configuration.

All of the devices must have a common ground.

If ground isolation is required, you can use the Isolated Repeater/Converter (IC655CCM590) in place of the Mini Converter.

When using the Mini Converter with a modem connection,

it may be necessary to jumper RTS to CTS (consult the user’s manual for your modem).

Cable Diagrams (Point-To-Point) When connecting the Mini Converter to IBM PC and compatible computers with hardware handshaking,

the following cable connections should be used.
