BI-0433

12 Channel Incremental Encoder Interface with Isolated Inputs and Cable Fault Detection

VMEbus

• VMEbus slave interface (A16;D16)
  
• Flexible base address selection
  
• Interrupter I(1-7)DYN
  
• Selectable address modifier decoding
  
• Occupies 256 memory locations
  

Channel Grouping

• Four independent groups of 3 channels
  
• Each group of channels shares:
  
  • a D25 front panel connector
    
  • an interrupt level
    
  • an interrupt vector
    
  • a fault detect delay register
    
  • a counter mode register
    
  • a device reset register
    
  • two CF32006 devices in a master/slave configuration
    

Channel Configuration

• Two quadrature inputs
  
• One index input
  
• One digital input
  
• Cable fault detection on all inputs
  
• One 32 bit up/down counter
  
• Interrupt on carry or borrow of the 32 bit up/down counter
  
• Direct digital input register
  
• Change of state detection circuit
  
• Interrupt mask register
  
• Enable index register
  
• Index status register
  

Input Signal Configuration

• Each input is galvanically isolated from the system
  
• Each input is galvanically isolated from any other input
  
• Differential or single ended configuration possible
