Prifibus Devices (Ci-800DP Series) / Ci-800 DP Remote Process Cluster Transmitter Back
 
 
   

The Remote Process Cluster Transmitter TM is an innovative product from Canopus Instruments suitable for transmitting a variety of analog signals from a cluster of process units on a single two wire Profibus-DP bus system. The transmitter can handle 8 process signals with channel-wise range & diagnostics selection through software. The process signals for which the inputs can be configured are 0- +5VDC , 0 - +10VDC, -5 to +5VDC , -10 to +10VDC and 4-20 ma DC . The integrated Profibus DP communications interface with configurable baud rates from 9.6Kbps to 12Mbps gives flexibility in connectivity to any Profibus - DP Master.
 
     
 

The complete software configurability for input signal types , range & diagnostics without jumper or DIP switch settings and the incorporation of the industry standard open fieldbus system PROFIBUS-DP facilitates quick set-up & integration with the main control system.

 
 

 

  
 

The transmitter is housed in a ABS Plastic enclosure with integrated 2.5mm sq terminal blocks for direct field cable termination. The transmitter can be mounted on a 35 mm standard DIN rail . A direct field mountable design in a die cast Aluminium enclosure is under development. This shall be suitable for mounting on a MS / SS pipe of suitable diameter.

 
 

 

  
  User benefits  
 

The transmitter provides enormous cost savings for those users wishing to migrate to a Fieldbus system from the traditional concept of direct field cabling of Analog transmitters. There is no need to changeover or upgrade the existing analog transmitters to smart transmitters or transmitters with fieldbus interfaces. Simply connect the existing analog transmitters to the Remote Process Cluster transmitter & convert the control system to a Fieldbus based system at barely 20% of the cost.
