The I-CR-R offers: 

• Improved controller communication reliability through redundancy for complex applications where the inter-controller bus is at risk of interruption  
• Support for sites with large footprint where there is a large physical distance between the ComAp controllers
• Duplicates the inter-controller CAN bus communication over a parallel RS485 interface 
  • In case the CAN or RS485 lines are interrupted, the others continue to maintain the overall system in operation
  • Support for up to 20 controllers on the inter-controller CAN bus  
• Doubling the useful range of inter-controller CAN bus
• Support for all ComAp controllers in our portfolio
  • The module is compatible with InteliGen 1000 and InteliMains 1010 controllers only if the CAN inter-controller communication mode is set to 32C/8C i.e., not in CAN FD mode
• UL certified
